23. A model of electroweakly interacting non-abelian vector dark matter

In this talk, we propose a new electroweakly interacting spin-1 dark matter (DM) model. We consider the non-Abelian extension of electroweak symmetry. Namely, we extend the SU(2)$_L$ group in the Standard Model (SM) into the direct products of three SU(2) groups. We also impose the exchange symmetry between two of these SU(2) groups to realize the spin-1 stable spectrum. In this setup, the DM...

We solve the Lindblad equation describing the Brownian motion of a Coulombic heavy quark-antiquark pair in a strongly coupled quark-gluon plasma using the highly efficient Monte Carlo wave-function method. The Lindblad equation has been derived in the framework of pNRQCD and fully accounts for the quantum and non-Abelian nature of the system. The hydrodynamics of the plasma is realistically...

In many dark matter models bound state transitions are fast. In a thermal bath, excited states contribute significantly to the effective annihilation cross section. Preliminary results indicate a dramatic change to the unitarity bound.

Title: Indirect search for dark matter bound state formation Abstract: Indirect searches for dark matter (DM) have conventionally been applied to the products of DM annihilation or decay. If DM couples to light force carriers, however, it can be captured into bound states via dissipation of energy that may yield detectable signals. We extend the indirect searches to DM bound state formation...

28. Thermal Real Scalar Triplet Dark Matter by Yu Watanabe

Real scalar triplet dark matter, which is known to be an attractive candidate for a thermal WIMP, is comprehensively studied paying particular attention to the Sommerfeldeffect on the dark matter annihilation caused by the weak interaction and the otherinteraction between the dark matter and the Higgs boson. We find a parameter region that includes the so-called ’WIMP-Miracle’ one is still...
