Abstract
We present the first preliminary results on photon multiplicity measurements at LHC at forward pseudorapidity (2.3<η<3.9) in proton-proton (pp) collisions at s=7TeV. The multiplicity distribution is found to be reasonably well explained by a double Negative Binomial Distribution (NBD). The average photon multiplicity increases logarithmically with s. It is found that none of the model we used (PYTHIA6D6T, PHOJET, and HERWIG) could explain the data.
