Probing feebly interacting dark matter with monojet searches

Jérôme Claude, Maíra Dutra, Stephen Godfrey

Dark matter may consist of feebly interacting massive particles (FIMPs) that never thermalized with the cosmic plasma. Their relic density is achieved via freeze-in for a wide rang…

Exploring Direct Detection Suppressed Regions in a Simple 2-Scalar Mediator Model of Scalar Dark Matter

Jérôme Claude, Stephen Godfrey

We explore regions of parameter space that give rise to suppressed direct detection cross sections in a simple model of scalar dark matter with a scalar portal that mixes with the…

Testing freeze-in with axial and vector bosons

Catarina Cosme, Maíra Dutra, Stephen Godfrey +1

The freeze-in production of Feebly Interacting Massive Particle (FIMP) dark matter in the early universe is an appealing alternative to the well-known - and constrained - Weakly In…

Multi-component dark matter from a hidden gauged SU(3)

Stephen Godfrey, Alexandre Poulin

We studied Dark Matter (DM) phenomenology with multiple DM species consisting of both scalar and vector DM particles in the Hidden Gauged SU(3) model of Arcadi et al. Because of th…

Spectroscopic Assignments of the Excited -Mesons

Stephen Godfrey, Kenneth Moats

Excited -mesons have been observed by the D0, CDF, LHCb and CMS experiments. We use the predictions of the relativized quark model to make quark model spectroscopic assignments…

The Belle II Physics Book

E. Kou, P. Urquijo, W. Altmannshofer +524

We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB collider. Belle II collected its first collisions in 2018, and is ex…
