The numerical results show that the total cross section with radion effects are abont . This could have inportant implications for radion searches and for the measurement of the cross - section of the Bhabha scattering. PACS number . Keywords radion Bhabha scattering.

INTRODUCTION As well known there are many convincing evidences that 80 of the matters in the universe is composed of dark matters DM . In several extensions of the Standard Model radion or u-boson is postulated 1-5 . On the other hand the Randall - Sundrum RS Model is one of the attractive condidates to solve the gauge hierarchy problem in the standard Model Many works have been done on the phenomenological aspects of radion in various colliders 6-9 . As we well known Bhabha scattering is among the key processes in particle physics. Recently the authors have presented the results of the SANC group on the complete one-loop calculation of the electroweak rediative corrections to Bhabha scattering with polarized beams 10 . Very recently we have investigated unparticle effects on Bhabha scattering 11 and on axion-like particles production in e e- collisions 12 . In this paper we investigate virtual radion effects via Bhabha scattering. TẠP CHÍ KHOA HỌC - Số 31 2019 II 69 2. RADION EXCHANGE AND CROSS SECTION In this cestion we will derive a formula for the cross-section of the process presented in which shows on of the possible processes where a radion may intermediate a creation of e e- in the e e- scattering.
