Differential cross section measurement

This study presents the differential cross section measurement for high-energy photon collisions using the GAMGAM7 and GAMJET10 models. We analyze input parameters from Monte Carlo simulations (MC) and compare results against invariant mass distributions (Mgg). The analysis is based on 36.2 pb⁻¹ of data, where statistical errors dominate. Results illustrate limitations in binning due to the MC input, particularly at low invariant mass regions. Ongoing work focuses on completing error propagation and examining pTg and pTgg distributions.

  1. Differential cross section measurement Remi Lafaye

  2. Input parameters from MC, vsMgg • Using GAMGAM7, GAMJET10 Low stat at small and high invariant mass will limit results GG sample results are used for the following quoted numbers

  3. Input parameters from MC, vsMgg • Using GAMGAM7, GAMJET10

  4. NAsignal Results, vsMgg • Using 36.2 pb-1 (data stat error only) • Binning is still limited by MC input at low Mgg

  5. Wgg L’L’ and TITI Results, vsMgg • Using 36.2 pb-1 (data stat error only) • Statisticalerrorfrom data isnow dominant everywhere

  6. Ongoing work • Finish error propagation • pTg and pTgg distributions
