Multi-component dark sectors: symmetries, asymmetries and conversions
نویسندگان
چکیده
A bstract We study the relic abundance of several stable particles from a generic dark sector, including possible presence asymmetries. After discussing different possibilities for stabilising multi-component matter, we analyse final symmetric and asymmetric matter components, paying special attention to role unavoidable conversions between states. find an exponential dependence asymmetries heavier components on annihilations conversions. conclude that having similar is natural outcome in many scenarios matter. This has novel phenomenological implications, which briefly discuss.

A New Direction in Dark-Matter Complementarity: Dark-Matter Decay as a Complementary Probe of Multi-Component Dark Sectors
In single-component theories of dark matter, the 2 → 2 amplitudes for dark-matter production, annihilation, and scattering can be related to each other through various crossing symmetries. These crossing relations lie at the heart of the celebrated complementarity which underpins different existing dark-matter search techniques and strategies. In multi-component theories of dark matter, by cont...
متن کاملSymmetries and asymmetries in chromatic discrimination.
Under conditions of adaptation to a steady neutral field (metameric to Daylight Illuminant D65), forced-choice thresholds for color discrimination were measured for brief targets presented to the human fovea. Measurements were made along +45° and -45° lines in a MacLeod-Boynton chromaticity space scaled so that the locus of unique yellow and unique blue lay at -45°. The lines were symmetrical r...
متن کاملMulti-Component Dark Matter Systems and Their Observation Prospects
Abstract Conversions and semi-annihilations of dark matter (DM) particles in addition to the standard DM annihilations are considered in a three-component DM system. We find that the relic abundance of DM can be very sensitive to these non-standard DM annihilation processes, which has been recently found for two-component DM systems. To consider a concrete model of a three-component DM system, ...
متن کاملSuperheavy Dark Matter with Discrete Gauge Symmetries
We show that there are discrete gauge symmetries protect naturally heavy X particles from decaying into the ordinary light particles in the supersymmetric standard model. This makes the proposal very attractive that the superheavy X particles constitute a part of the dark matter in the present universe. It is more interesting that there are a class of discrete gauge symmetries which naturally a...
متن کاملDirect Conversions among Multi-Granularity Temporal Constraints
Temporal constraints are part of the specification of many complex application frameworks including planning, scheduling, real-time systems, workflow and cooperative systems. This paper investigates the problem of converting among quantitative temporal constraints expressed in terms of different time granularities. An expressive formal model for time granularities is assumed including common gr...
