Spectator Processes and Baryogenesis
Spectator processes which are in thermal equilibrium during the period of baryogenesis influence the final baryon asymmetry. We study this effect quantitatively for thermal leptogenesis where we find a suppression by a factor O(1). The cosmological baryon asymmetry is naturally explained by thermal leptogenesis, i.e. the out-of-equilibrium decays of heavy Majorana neutrinos [1]. This mechanism ...
متن کاملYukawa and Tri-scalar Processes in Electroweak Baryogenesis
Abstract We derive the contributions to the quantum transport equations for electroweak baryogenesis due to decays and inverse decays induced by tri-scalar and Yukawa interactions. In the Minimal Supersymmetric Standard Model (MSSM), these contributions give rise to couplings between Higgs and fermion supermultiplet densities, thereby communicating the effects of CP-violation in the Higgs secto...
متن کامل∆-Scaling in Spectator Fragmentation
Universal scaling-laws of fluctuations (the ∆-scaling laws) have been derived for equilibrium systems, and shown to apply also in certain out-of-equilibrium situations. [1]. Recently looking for signals of a phase transition in multifragmentation reactions the model-independent theory of universal fluctuation has been used [2]. The ∆-scaling is observed when two or more probability distribution...
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 کاملFacing the Spectator
We investigated the familiar phenomenon of the uncanny feeling that represented people in frontal pose invariably appear to "face you" from wherever you stand. We deploy two different methods. The stimuli include the conventional one-a flat portrait rocking back and forth about a vertical axis-augmented with two novel variations. In one alternative, the portrait frame rotates whereas the actual...
