Filtered baryogenesis

چکیده
A bstract We propose a new mechanism to simultaneously explain the observed dark matter abundance and baryon asymmetry of Universe. The is based on Filtered Dark Matter scenario, where particles acquire large mass during first-order phase transition. This implies that only small fraction them are energetic enough enter advancing true vacuum bubbles survive until today, while rest reflected annihilate away quickly. supplement this scenario with CP-violating interaction, which creates chiral in population particles. In false phase, portal interaction quickly converts sector into Standard Model lepton asymmetry. then partially converted by standard electroweak sphaleron processes. discuss dependence generated parameters model for two different interactions demonstrate successful baryogenesis both. For one portals, it also possible abundance, over many orders magnitude mass.

Gravitational baryogenesis.
We show that a gravitational interaction between the derivative of the Ricci scalar curvature and the baryon-number current dynamically breaks CPT in an expanding Universe and, combined with baryon-number-violating interactions, can drive the Universe towards an equilibrium baryon asymmetry that is observationally acceptable.
متن کاملElectroweak Baryogenesis with Cosmic Strings? Electroweak Baryogenesis with Cosmic Strings?
I report on a critical analysis of the scenario of electroweak baryoge-nesis mediated by nonsuperconducting cosmic strings. This mechanism relies upon electroweak symmetry restoration in a region around cosmic strings, where sphalerons would be unsuppressed. I discuss the various problems this scenario has to face, presenting a careful computation of the sphaleron rates inside the strings, of t...
متن کاملInflation, Neutrino Baryogenesis, and (S)Neutrino-Induced Baryogenesis
We evaluate the constraints that the COBE observations put on baryogenesis in inflationary cosmologies.We consider the supersymmetric version of the proposal of Fukugita and Yanagida, that the baryon asymmetry of the universe is created by nonperturbative electroweak reprocessing of a lepton asymmetry generated in the decay of heavy right handed see-saw (s)neutrinos. We review our recent propos...
متن کاملA Filtered Reference – Filtered Error LMS Algorithm
Adaptive filters updated by the least mean square (LMS) algorithm are succesfully implemented in digital control systems. They are utilized for both plant identification and control purposes. In control appications (e.g. in active noise control) the output of the adaptive filter drives the plant input, and the error signal is derived only at the output of the plant. In such cases the filtered r...
متن کاملGUT, Neutrinos, and Baryogenesis
It is an exciting time for flavor physics. In this talk, I discuss recent topics in baryogenesis and leptogenesis in light of new data, and implications in B and neutrino physics. I also discuss current situation of grand unified theories concerning coupling unification, proton decay, and indirect consequences in lepton flavor violation and B physics. I explain attempts to understand the origin...
