Inflaton freeze-out
نویسندگان
چکیده
We study the possibility that, after inflation,the inflaton reaches thermal equilibrium with Standard Model bath and eventually freezes out in nonrelativistic regime. When decay is sole source of (nonthermal) dark matter, its relic density automatically suppressed. delineate parameter space leading to correct matter abundance. The model allows for a significant Higgs-inflaton coupling which may lead invisible Higgs into pairs at LHC.

Freeze-out dynamics at RHIC
Investigation of the final hadronic state properties of ultrarelativistics pp and Au+Au collisions supplies information on freeze-out conditions at RHIC and possible insights into early stages of these collisions. A variety of particle spectra measured by STAR are studied within the framework of chemical and local kinetic equlibrium models. Here we present the extracted chemical and final kinet...
متن کاملFreeze-out configuration in multifragmentation
The excitation energy and the nuclear density at the time of breakup are extracted for the α + Au reaction at beam energies of 1 and 3.6 GeV/nucleon. These quantities are calculated from the average relative velocity of intermediate mass fragments (IMF) at large correlation angles as a function of the multiplicity of IMFs using a statistical model coupled with many-body Coulomb trajectory calcu...
متن کاملContinuous decoupling and freeze-out∗
The decoupling and freeze-out of energetic nuclear collisions is analysed in terms of transparent semi-classical decoupling formulae. They provide a smooth transition and generalise frequently employed instantaneous freeze-out procedures. Simple relations between the damping width and the duration of the decoupling process are presented and the implications on various physical phenomena arising...

متن کاملShock-like Freeze-out in Relativistic Hydrodynamics
We have formulated a self-consistent model of freeze-out on an arbitrary hypersurface. It conserves energy and momentum across the discontinuity between ideal fluid and the gas of free particles. Energy and momentum of those free particles have non-equilibrium values that could be a signal for the formation of hot and dense matter in heavy ion collisions.
