Light Dark Matter from Entropy Dilution
We show that a thermal relic which decouples from the standard model (SM) plasma while relativistic can be a viable dark matter (DM) candidate, if the decoupling is followed by a period of entropy dilution that heats up the SM, but not the dark sector ...

Opening up the QCD axion window
We present a new mechanism to deplete the energy density of the QCD axion, making decay constants as high as f[subscript a] ≃ 1017 GeV viable for generic initial conditions.

From oversimplified to overlooked: the case for exploring Rich Dark Sectors [PDF]
The Standard Model (SM) of particle physics provides a very successful description of fundamental particles and their interactions but it is incomplete, as neutrino masses, dark matter and the baryon asymmetry of the Universe indicate.

Minimal models for dark matter and the muon g − 2 anomaly
We construct models with minimal field content that can simultaneously explain the muon g − 2 anomaly and give the correct dark matter relic abundance. These models fall into two general classes, whether or not the new fields couple to the Higgs. For the

Unitarity limits on thermal dark matter in (non-)standard cosmologies
Using the upper bound on the inelastic reaction cross-section implied by S-matrix unitarity, we derive the thermally averaged maximum dark matter (DM) annihilation rate for general k → 2 number-changing reactions, with k ≥ 2, taking place either entirely

Physics Beyond the Standard Model [PDF]
I have been assigned this broad title but my talk will be mostly concerned with the origin ofthe electroweak scale. I will attempt to give an overview of the theoretical ‘laborings’ thatcame up after the end of the LEP era and in preparation to the ...

New decay channels for the neutron into dark matter plus other particles have been suggested for explaining a long-standing discrepancy between the neutron lifetime measured from trapped neutrons versus those decaying in flight.

General Framework of Automorphic Inflation [PDF]
Automorphic inflation is an application of the framework of automorphic scalar field theory, based on the theory of automorphic forms and representations.

Scalable Computation of Topological Abstractions for Scalar Data
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Maximal value for trilinear Higgs coupling in a 3-3-1 EFT [PDF]
Recent efforts, both theoretical and experimental, have increasingly focused on the scalar potential of the Standard Model, with a highlight on the trilinear Higgs coupling.
