  1. GOAL: Model-independent spin determination of resonant boson (H, Z’, G,…) production via Drell-Yan pp -> γγ X at LHC S. Dalley & P. Nadolsky, Dept. Physics, SMU Spin of Resonant Boson Production at LHC Osland, Pankov, Paver, Tsytrinov, QCD LO Boson dσ/dz “Center-Edge” Asymmetry in pp -> l l X [hep-ph/0805.2734] Center-Edge Asymmetry in z = cos θ*

  2. What do we know about γγ? SM & Scalar Bosons (Higgs): • Balazs, Berger, Nadolsky, Yuan, QCD NLO + NLL Resummation for SM + Higgs dσ/dΦ in pp -> γγ X [hep-ph/0704.0001] ResBos: Standard toolfor Higgs searches Vector Bosons: No contribution to γγfinal state Tensor Bosons (KK-Gravitons): • Kumar, Matthews, Ravindran, Tripathi, NLO QCD + Graviton dσ/dΦ in pp -> γγ X [hep-ph/0902.4894] • Li, Li, Yang, NLO QCD + Resum + Graviton total σ[hep-ph/0606045]

  3. z = cos θ* dependence in LO QCD No cuts, no SM background. Assume gg PDF dominates. dσ/dz • To-Do Summary: include QCD NLO + NLL Resummation of initial state radiation for Spin-2 resonance in pp→ γγX in RESBOS (dσ/dΦ), include exp and theory cuts, compare ACEfor scalar and tensor resonances @ LHC Tensor → γγ ACE = σCE/σ Scalar Tensor →l l Tensor → l l z* z Tensor → γγ
