Description
I give the results of a detailed reanalysis of the 13 TeV TOTEM measurement of the differential elastic cross section at very low momentum transfer. We obtain estimates similar to thos of TOTEM for the rho parameter, but a significantly lower total cross section. I then discuss whether these results imply the existence of an charge-parity-odd exchange, the odderon, at t=0. This seminar is based on arXiv:1901.05863.
