  1. STUDYING SOME PROCESSES, WHICH ARE CHARACTERIZED BY THE PRODUCTION OF MUON IN THE FINAL STATE NIKOLAEV Kirill ILYUSHENKA Yauheni Laboratori Nazionali di Frascati, November 2005

  2. pile-up: Z0,W ±: Heavy Quark: H0: Simulations have been done by means of Monte Carlo package – PYTHIA (v 6.324) 1) elastic scattering single diffraction double diffraction inelastic scattering 2) Z0 production 4) cc production 7) H0 production 3) W± production 5) bb production 8) H0W ± or H0Z0 6) tt production

  3. For each processes have been generated 100 000 events • 1 event if: • PTR (muons) > 0.5 (3.5) GeV • |pseudorapidity| < 3.8 • Number of muons >=1 • VTR < 100 mm Output data file contains: Muons information: Nmu muonID E Px Py Pz X Y Z pseudorapidity Sig All mother particles information for each muons: Nmothers motherID Emother Pxmother Pxmother Pxmother Xmother Ymother Zmother

  4. CASTOR (CERN): • Process simulation • Convert data from ntuple into root format Output data files information: • Local machine (LNF): • Merge data files for current process into one • Make data analysis *CPU time=average(Nfile(Nevent=10 000)=10) **File size=average(Nfile(Nevent=10 000)=10)

  5. Comparing results of our simulations with ATLAS TDR Differential cross-section for W+ and W- production as a function of the vector boson rapidity yW. Points – some reference points from ATLAS TDR (v2, p518)

  6. Comparing results of our simulations with ATLAS TDR Differential cross-section for W+ and W- production as a function of the pseudorapidity ημ (|ηl|<2.5, P┴l>20GeV, ETmiss>20GeV). Points – some reference points from ATLAS TDR (v2, p518)

  7. Comparing results of our simulations with ATLAS TDR Differential cross-section for W+ and W- production as a function of the transverse momentum P┴W. (|ηl|<2.5, P┴l>20GeV, ETmiss>20GeV). Points – some reference points from ATLAS TDR (v2, p519)

  8. Comparing results of our simulations with ATLAS TDR Differential cross-section for Z production as a function of the transverse momentum P┴Z. (|ημ|<2.5, P┴μ>20GeV). Points – some reference points from ATLAS TDR (v2, p522)

  9. Data from Z0 : |ημ| < 2.7, P┴μ > 6.5 GeV

  10. Data from W+ production: |ημ| < 2.7, P┴μ > 6.5 GeV

  11. Data from W- production: |ημ| < 2.7, P┴μ > 6.5 GeV

  12. Data from cc production: |ημ| < 2.7, P┴μ > 6.5 GeV

  13. Data from bb production: |ημ| < 2.7, P┴μ > 6.5 GeV

  14. Data from tt production: |ημ| < 2.7, P┴μ > 6.5 GeV

  15. Data from H0 production: |ημ| < 2.7, P┴μ > 6.5 GeV

  16. Data from H0W ± or H0Z0 production: |ημ| < 2.7, P┴μ > 6.5 GeV

  17. Data from pileup production: |ημ| < 2.7, P┴μ > 6.5 GeV

  18. Have been done: • Main simulation program for different processes • Data generation for each process • Comparing our results with ATLAS TDR • Basic data analysis • In future: • To finish data analysis • To continue data generation • To understand the difference between our results and ATLAS TDR
