Feasibility studies of proton electromagnetic form factors with the PANDA detector — •Dmitry Khaneft — KPH, Mainz University, Mainz, Germany — HIM, Mainz, Germany
Perspectives of measuring the proton electromagnetic form factors in the time-like region with the PANDA detector at the FAIR facility are presented. First simulations using the PANDAroot simulation framework for both the signal pp → e+e− and main background pp → π+π− channel have been performed. For the simulation of signal events, the hypotheses for the ratio of the electric and magnetic Sachs form factors |GE|/|GM|=0,1,3 have been considered independently for a number of pp center of mass energy values. Based on the simulation results, an efficient set of selection cuts to discriminate signal from background has been developed. Preliminary results on background suppression factors are shown.
