Dark matter admixed neutron stars [PDF]

Physical Review D, 2021
Neutron stars could contain a mixture of ordinary nuclear matter and dark matter, such that dark matter could influence observable properties of the star, such as its mass and radius.

GRB 181110A: Constraining the Jet Structure, Circumburst Medium and the Initial Lorentz Factor

Universe, 2022
The afterglow data of gamma ray bursts (GRBs) can be used to constrain the physical properties of the fireball (e.g., the jet structure and opening angle) and the circumburst medium.

An Unsupervised Machine Learning Method for Electron–Proton Discrimination of the DAMPE Experiment

Universe, 2022
Galactic cosmic rays are mostly made up of energetic nuclei, with less than 1% of electrons (and positrons). Precise measurement of the electron and positron component requires a very efficient method to reject the nuclei background, mainly protons.

Global QCD analysis and dark photons

Journal of High Energy Physics, 2023
We perform a global QCD analysis of high energy scattering data within the JAM Monte Carlo framework, including a coupling to a dark photon that augments the Standard Model (SM) electroweak coupling via kinetic mixing with the hypercharge B boson.

Ultra-light dark matter [PDF]

The Astronomy and Astrophysics Review, 2020
Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by bosons with masses ranging from $$10^{-24}\, \mathrm {eV}< m < \mathrm {eV}$$ 10 - 24 eV < m < eV . These models have been receiving a lot of attention in the past few
