We are pleased to announce that the next ITMP seminar will be held on Wednesday, October 07, at 18:00. The seminar will be arranged via Zoom.
Speaker: Ariel Arza, ITMP
Title: Production of massive particles from the decay of a free massless field
Abstract: In this talk we will show, in a simple toy model (H=g\phi\chi^2), how Bose enhancement allows the decay of a massless field into massive particles. It happens due to a parametric resonance caused by a big energy density of the decaying field. I will show the instability conditions as well as the energy density threshold for the decay to occur. I will also compute the equivalent of the spontaneous decay rate.
If you want to join the seminar please register here before 14:00, October 07.
