DESCRIPTION:Speakers: Динмухаммед Жамбыл ()\nOne of the k
 nown mechanism for primordial black holes formation is based on the collap
 se of closed domain walls in the early Universe. The domain walls arise fr
 om multiple scalar field fluctuations during the inflationary stage. Two a
 pproaches exist for describing this process: the massless field and the ma
 ssive field approximation. This paper explores both approximations. The ma
 ss spectra of the forming primordial black holes are derived and compared 
 for both cases. In addition\, the conditions of applicability for each app
 roach are discussed.\n\nhttps://indico.particle.mephi.ru/event/626/contrib
