From QFT to Boltzmann: Freeze-in in the presence of oscillating condensates
Wen-Yuan Ai, Ankit Beniwal, Angelo Maggi +1
Scalar dark matter (DM), and axions in particular, have an irreducible abundance of particles produced by freeze-in due to portal interactions with the Standard Model plasma in the…
Collider constraints on electroweakinos in the presence of a light gravitino
The GAMBIT Collaboration, Viktor Ananyev, Csaba Balázs +19
Using the GAMBIT global fitting framework, we constrain the MSSM with an eV-scale gravitino as the lightest supersymmetric particle, and the six electroweakinos (neutralinos and ch…
Global Fits of Dirac Dark Matter Effective Field Theories
Ankit Beniwal
In this proceeding, we present results from a global fit of Dirac fermion dark matter (DM) effective field theory (EFT) based on arXiv:2106.02056 using the GAMBIT framework. Here w…
Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
Global fit of 2HDM with future collider results
Ankit Beniwal, Filip Rajec, Markus Tobias Prim +5
In this work, we summarize a global fit study of Type-II two Higgs doublet models (2HDM), and explore the impact of future SM-like Higgs and Z-pole precision measurements on the al…
Thermal WIMPs and the Scale of New Physics: Global Fits of Dirac Dark Matter Effective Field Theories
The GAMBIT Collaboration, Peter Athron, Neal Avis Kozar +24
We assess the status of a wide class of WIMP dark matter (DM) models in light of the latest experimental results using the global fitting framework . We perform a…
Simple and statistically sound recommendations for analysing physical theories
Shehu S. AbdusSalam, Fruzsina J. Agocs, Benjamin C. Allanach +72
Physical theories that depend on many parameters or are tested against data from many different experiments pose unique challenges to statistical inference. Many models in particle…
The ScotoSinglet Model: A Scalar Singlet Extension of the Scotogenic Model
Ankit Beniwal, Juan Herrero-García, Nicholas Leerdam +2
The Scotogenic Model is one of the most minimal models to account for both neutrino masses and dark matter (DM). In this model, neutrino masses are generated at the one-loop level,…
Global fits of axion-like particles to XENON1T and astrophysical data
Peter Athron, Csaba Balázs, Ankit Beniwal +13
The excess of electron recoil events seen by the XENON1T experiment has been interpreted as a potential signal of axion-like particles (ALPs), either produced in the Sun, or consti…
Global fit of pseudo-Nambu-Goldstone Dark Matter
Chiara Arina, Ankit Beniwal, Céline Degrande +2
We perform a global fit within the pseudo-Nambu-Goldstone dark matter (DM) model emerging from an additional complex scalar singlet with a softly broken global U(1) symmetry. Leadi…
Global study of effective Higgs portal dark matter models using GAMBIT
Ankit Beniwal
In this proceeding, we present frequentist and Bayesian results from a global fit of effective vector and Majorana fermion Higgs portal dark matter (DM) models using the $\mathsf{G…
Neutrinos and gamma rays from long-lived mediator decays in the Sun
Carl Niblaeus, Ankit Beniwal, Joakim Edsjo
We investigate a scenario where dark matter (DM) particles can be captured and accumulate in the Sun, and subsequently annihilate into a pair of long-lived mediators. These mediato…
Gravitational waves and electroweak baryogenesis in a global study of the extended scalar singlet model
Ankit Beniwal, Marek Lewicki, Martin White +1
We perform a global fit of the extended scalar singlet model with a fermionic dark matter (DM) candidate. Using the most up-to-date results from the measured DM r…
A global study of the extended scalar singlet model
Ankit Beniwal, Marek Lewicki, Martin White +1
We present preliminary results from a global study of the extended scalar singlet model with a fermionic dark matter (DM) candidate. In addition to requiring a successful electrowe…
Global analyses of Higgs portal singlet dark matter models using GAMBIT
The GAMBIT Collaboration, Peter Athron, Csaba Balázs +15
We present global analyses of effective Higgs portal dark matter models in the frequentist and Bayesian statistical frameworks. Complementing earlier studies of the scalar Higgs po…
Gravitational wave, collider and dark matter signals from a scalar singlet electroweak baryogenesis
Ankit Beniwal, Marek Lewicki, James D. Wells +2
We analyse a simple extension of the SM with just an additional scalar singlet coupled to the Higgs boson. We discuss the possible probes for electroweak baryogenesis in this model…
Combined analysis of effective Higgs portal dark matter models
Ankit Beniwal, Filip Rajec, Christopher Savage +4
We combine and extend the analyses of effective scalar, vector, Majorana and Dirac fermion Higgs portal models of dark matter (DM), in which DM couples to the Standard Model (SM) H…
