Particle-antiparticle asymmetries from annihilations

I Baldes, NF Bell, K Petraki, RR Volkas

2014-10-30

An extensively studied mechanism to create particle-antiparticle asymmetries is the out-of-equilibrium and CP violating decay of a..

Grand unified hidden-sector dark matter

SJ Lonsdale, RR Volkas

2014-10-01

We explore G×G unified theories with the visible and the hidden or dark sectors paired under a Z2 symmetry. Developing a system of..

Leptophilic dark matter with Z′ interactions

NF Bell, Y Cai, RK Leane, AD Medina

2014-08-28

We consider a scenario where dark matter (DM) interacts exclusively with Standard Model leptons at tree level. Because of the abse..

Co-annihilating dark matter: Effective operator analysis and collider phenomenology

NF Bell, Y Cai, AD Medina

2014-06-02

We study dark matter (DM) models in which there are two dark sector particles, χ1 and χ2, of near mass. In such models, co-annihil..

A solvable model of interacting many body systems exhibiting a breakdown of the boltzmann equation

BHJ McKellar

2014-01-30

In a particular exactly solvable model of an interacting system, the Boltzmann equation predicts a constant single particle densit..
