  3. ProjectGDH&SPASCHARM Yu.Usov A.Kovalik Study of the nucleon spin structure in strong and electromagnetic interactions The main JINR contribution consists in development, construction and maintenance of the polarized targets for spin studies at the accelerators MAMI (Mainz) and U-70 in Protvino. Both transverse and longitudinal polarization of protons or deuterons is provided in the frozen-spin targetwith a maximum polarization 90% for protons and 80% for deuterons. A.Kulikov PAC 25.01.2017

In the past the JINR group has made a large contribution in this setup: Forward Detector (FD) with scintillation hodoscope and wire chambers, part of trigger electronics and electronics of the silicon detector (STT). Data analysis and a corresponding software to a large extent is provided by the JINR group. A.Kulikov PAC 25.01.2017

  9. Investigation of near-threshold p-meson production, pp{pp}sp0,pn{pp}sp -, in the single and double polarization modes made it possible to fulfill the partial wave analysis in order to clarify the role of the contact operator important in the chiral perturbation theory.

  10. Recently, studying the process pp  {pp}sp0 two resonance states in the isovector two-baryon system with a mass of 2.2 GeV/c2 have been observed, 3P2d (2-) and3P0s (0-) . Here the resonance 3P0s (0-) is a new one, observed for the first time. Note that since 80s there were known only three isovector NN resonances 1D2 , 3F3 , 3P2, therefore discovery of a new resonance is rather rare occasion. V.Komarov et al. Phys.Rev.

  12. In total, only within the last years experimental results of ANKE were published in 15papers (in Phys.Lett.B, Phys.Rev.C, Eur.Phys.Jour.A), in many of them the contribution of JINR is decisive. At ANKE there were prepared 6 diploma and 3 PhD theses, 2 more PhD are close to finalizing, ANKE results were partly used in 3 doctoral theses. Since 2015 operation of COSY for hadron physics has been terminated and ANKE is now dismantled. A.Kulikov PAC 25.01.2017

Since 2015 operation of COSY for hadron physics has been terminated and ANKE is now dismantled. But there is a lot of data collected in the last decade still not analyzed. Therefore, we are planning to continue data analysis. ANKE+COSY is a unique on the world-wide scale complex for spin studies at intermediate energies, and one has to extract as much as possible information from the collected data.

  14. Results Another part of SPRING is preparation for the PAX experiment aimed at studies with polarized antiprotons. Spin-filtering method for polarization of the beam has been tested in 2012-2014 and the experimental result agrees with the theoretical prediction (building up of the transversal polarization). W.Augustyniak et al. Phys. Lett. B 718 (2012) 64. D.Oellers et al. NIM A 759 (2014) 6. C.Weidemann et al.Phys. Rev. ST-AB 18 (2015) 020101. Beam measurements on thePAXprogram could be continued when the Siberian snake is implemented in the COSY ring. This would test the spin-filtering method for longitudinal polarization.

A sizable EDM would mean manifestation of so-called “new physics” beyond the Standard Model. + exp. limits Permanent EDMs violate P and T. Assuming CPT to hold, CP violated also.

A sizable EDM would mean manifestation of so-called “new physics” beyond the Standard Model. + exp. limits Permanent EDMs violate P and T. Assuming CPT to hold, CP violated also. Observation of EDM is possible via detection of a tiny polarization arising in an initially unpolarized beam. As a consequence, the experiment makes very high demands to accelerator performance in terms of beam lifetime, polarization lifetime and other beam parameters. A.Kulikov PAC 25.01.2017

  19. In total, in 2012-2016 there were published 28 papers on SPRING in the world physics journals, the JINR physicists gave 13 talks at the international conferences. It is proposed to continue the works on the SPRING program in the form of activity within the theme in order to complete analysis of the collected data. A.Kulikov PAC 25.01.2017

  20. ProjectCOMET (COherentMuon-to-Electron Transition) Z.Tsamalaidze The goal is a search for neutrino-less conversion of a muon to an electron, m- + N(A,Z)  e- + N(A,Z) with sensitivity 10-16 - 10-17, what is 4 orders of magnitude better than the current value search for physics beyond the Standard Model JINR participates in construction of the straw-tube tracker, crystal electromagneticcalorimeter, in engineering design, in different kind of simulations. A.Kulikov PAC 25.01.2017

  21. The DLNP JINR group successfully fulfilled R&D in order to update the developed in VBLHEP technology for production of very thin straw tubes required in COMET. As a result, a complete set of thin-wall (20m) tubes of 9.8 mm diameter has been produced in 2015 for Phase-1 of the experiment (> 2700 tubes)and delivered to Japan for the detector assembling For Phase-2 even thinner (12m) and less diameter tubes (ᴓ 5 мм)are required. With this aim new R&D studies should be done by the JINR-COMET group. Participation in the engineering design A.Kulikov PAC 25.01.2017

  22. In order to select the crystal type for ECAL, tests of the calorimeter prototypes with the LYSO and GSO crystals were carried out in 2014 at the electron beam of the accelerator in Tohoku with our participation. Data analyses fulfilled independently in Japan and Dubna have demonstrated the advantages of the LYSO type which finally was selected as the type to be used in the calorimeter. A new test bench has been prepared in DLNP for tests of the crystals. A.Kulikov PAC 25.01.2017

  24. Experiment TRITON D.Demin Experiment TRITON at Phasotron DLNP studies the nuclear fusion reactions in the ptµ system. Systematic studies of the muon catalysis have started in Dubna since 1964 and stimulated research activity in this field in many laboratories all over the world. Among different muon catalysed reactions (pd, dd, dt, tt, pt) only in the pt-fusion a strong disagreement between experimental yields(in a single measurement of PSI, 1993) and theoretical predictions was observed. Project TRITON was proposed by DLNP in 2011 in order to resolve this problem. ptμ = 4Heμ+γ+19,82 MeV (Eγ = 19.77 MeV),(1) ptμ = 4He + μ + 19,81 MeV (Eμ = 19.22 MeV, (2) ptμ = 4Heμ + e+ + e– + 18,79 MeV (3) discrepancy 8 times discrepancy ~ 300 times not observed at all P S I results A.Kulikov PAC 25.01.2017

  25. In May 2016 the beam measurements were successfully carried out in DLNP with a tritium target (0.8% tritium in a T/H liquid mixture of 50 cm3 volume). All three reaction channels have been detected, plus an indication to a new, the fourth one, with emission of two gamma- quanta: ptμ = 4Heμ + γ + γ e+e- energy spectrim The summed energy of two gammas A.Kulikov PAC 25.01.2017

  26. Preliminary results of the May run presented at the previous PAC meeting • The yields of the channels with emission of a single gamma ptμ = 4Heμ+γ+19,82 MeVor a muon ptμ = 4He +μ +19,81 MeVagree with the results of the PSI group. • Thus, contradiction with theory still remains. • For the first time in the pt-fusion reaction, the channel with emission of e+e- pairs • was detected: • ptμ = 4Heμ + e+ + e– + 18,79 MeV • The yield is compatible with the theoretical predictions of Ya.B. Zel'dovich and • S.S. Gershtein (1960) for this channel. • For the first time an indication was obtained to existence of a new reaction channel with emission of a pair of gammas: ptμ = 4Heμ + γ + γ + 19,82 MeV A.Kulikov PAC 25.01.2017

  27. Following the PAC recommendation, in November 2016 another beam measurements were fulfilled with a different tritium concentration (0.08% tritium in the T/H mixture) and in two different detector geometries Results (preliminary!) of the November run: • Predictions about the dependence of the reaction yield • on the tritium concentration have been confirmed. • Existence of a new reaction channel with emission • of two gamma-quanta has been confirmed. • Measurements with different detector geometries • have shown existence of an angular correlation of • the e+ and e- emission, and an absence of such • correlation in emission of two gammas. • This allows to make conclusions about the transition • type.

It is proposed to continue TRITON as activity within the theme. A.Kulikov PAC 25.01.2017

  29. Experiment MEG-PEN N.Kuchinsky MEG-PEN – high precision study of rare and forbidden decays of muons and pions. The decaysp+ e+nи m+ е+ g have been studied at the setups PIBETA and MEG (PSI), respectively. The data taking is finished, and analysis is in progress. JINR has made a large contribution in the setupPIBETA: cylindrical proportional chambers with electronics, CsI crystals,miniature time projection chamber (mTPC) developed in JINR especially for this experiment. ForMEGthe drift chambers have been constructed with the JINR participation. A.Kulikov PAC 25.01.2017

  30. Data analysis on the decayp+ e+nwhere JINR is actively participating is close to finishing. A total statistics amounts to 2.3∙107events. The final results on this decay are foreseen in the first half of 2017. The expected relative precision is ΔBR/BR ≈ 5·10-4  5 times improvement. In 2016 two papers were published on measurement of the muon beam polarization, Pµ = −0.86 ± 0.02 (stat) +0.05 -0.06 (syst) and the branching ratio of the muon radiative decay, BR(m→enenmg) = (6.03±0.14stat±0.53sys)×10−8. These data were necessary for obtaining the final result for the decaym+ е+g. Using a full collected statistics, new upper limit of m+ е+gdecay has been established, BR(µ+ → e+γ) < 4.2 × 10−13 . This result improves the previous value of the same group by a factor ~1.4. A.M.Baldini et al. Eur.Phys.Jour.C (2016) 76:434. A.Kulikov PAC 25.01.2017
