The number of production events obtained for different collision energies is calculated for an integrated luminosity of 100 1 fbar yearly. | Scientific Journal - N 3S 2O19 II 35 PHOTON PAIR PRODUCTION IN ee COLLISION AT ILC Bui Thi Ha Giang1 Dang Van Soa2 1Hanoi National University of Education 2Hanoi Metropolitian University Abstract Our work has based on the Randall-Sundrum model RS . The total crosssection in photon pair production at e e collision achieves the maximum value when the polarization of electron positron beams are Pe 1 Pe -1 or Pe- -1 Pe 1 at International Linear Colliders ILC . The number of production events obtained for different collision energies is calculated for an integrated luminosity of 100 fbar 1 yearly. Keywords photon pair production Randall-Sundrum model ILC.

INTRODUCTION The RS model which was suggested in 1999 has presented the attractive phenomenology including Dark Matter candidates 1-3 . The RS setup involves two 3-branes UV 3-brane and IR 3-brane. Gravity is localized UV brane while the Standard Model SM fields are supposed to be localized IR brane. The separation between the two 3-branes leads directly to the existence of an additional scalar called the radion corresponding to the quantum fluctuations of the distance between the two 3-branes 1 . The observed boson discovered by the ATLAS and CMS collaborations in 2012 4 5 is 125 GeV. However it may not be the Standard model SM Higgs 6-9 . Therefore in this work the influence of the 125 GeV Higgs radion on the photon pair production at the high energy has been studied. In addition at the high energy TeV scale the scale invariant sector has been considered as an effective theory and that if it exists it is made of unparticle suggested by Geogri 10 11 . Based on the Geogri s idea unparticle physics has been mentioned with the extra dimension as the RS model 12 13 . The effects of unparticle on properties of high energy colliders have been intensively studied in Refs. 12-22 . Recently the possibility of the unparticle has .
