Baryon number freeze-out in the Standard Model, precisely
Cristina Benso, Dietrich Bödeker, Kohei Kamada +4
Weak sphaleron transitions turn a lepton asymmetry of the Standard Model plasma in the early Universe into a baryon asymmetry, conserving baryon-minus-lepton number and its i…
Combined constraints on dark photons from high-energy collisions, cosmology, and astrophysics
A. W. Romero Jorge, L. Sagunski, Guan-Wen Yuan +2
We investigate a dark sector coupled to the Standard Model (SM) through a kinetically mixed dark photon associated with a new gauge symmetry. Kinetic mixing $\varepsilo…
Constraints on Kinetic Mixing of Dark Photons from Dilepton Spectra
A. W. Romero Jorge, E. Bratkovskaya, T. Song +1
Dark photons, the hypothetical gauge bosons associated with an additional symmetry, can couple to Standard Model particles through a small kinetic mixing parameter…
Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy-Ion Collisions
Adrian William Romero Jorge, Elena Bratkovskaya, Taesoo Song +1
Vector -bosons, often referred to as 'dark photons', are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical…
Search for dark photons in heavy-ion collisions
Adrian William Romero Jorge, Elena Bratkovskaya, Laura Sagunski
The vector -bosons, or so called 'dark photons', are one of the possible candidates for the dark matter mediators. We present a procedure to derive theoretical constraints on th…
QCD-sourced tachyonic phase transition in a supercooled Universe
Daniel Schmitt, Laura Sagunski
We propose a novel gravitational wave production mechanism in the context of quasi-conformal Standard Model extensions, which provide a way to dynamically generate the electroweak…
Impact of theoretical uncertainties on model parameter reconstruction from GW signals sourced by cosmological phase transitions
Marek Lewicki, Marco Merchand, Laura Sagunski +2
Different computational techniques for cosmological phase transition parameters can impact the Gravitational Wave (GW) spectra predicted in a given particle physics model. To scrut…
Supercool exit: Gravitational waves from QCD-triggered conformal symmetry breaking
Laura Sagunski, Philipp Schicho, Daniel Schmitt
Classically conformal Standard Model extensions predict an intriguing thermal history of the early universe. In contrast to the common paradigm, the onset of the electroweak phase…
Dark Matter In Extreme Astrophysical Environments
Masha Baryakhtar, Regina Caputo, Djuna Croon +37
Exploring dark matter via observations of extreme astrophysical environments -- defined here as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well…
First Constraints on Nuclear Coupling of Axionlike Particles from the Binary Neutron Star Gravitational Wave Event GW170817
Jun Zhang, Zhenwei Lyu, Junwu Huang +4
Light axion fields, if they exist, can be sourced by neutron stars due to their coupling to nuclear matter, and play a role in binary neutron star mergers. We report on a search fo…
The Semi-Classical Regime for Dark Matter Self-Interactions
Brian Colquhoun, Saniya Heeba, Felix Kahlhoefer +2
Many particle physics models for dark matter self-interactions - motivated to address long-standing challenges to the collisionless cold dark matter paradigm - fall within the semi…
Prospects for axion searches with Advanced LIGO through binary mergers
Junwu Huang, Matthew C. Johnson, Laura Sagunski +2
The observation of gravitational waves from a binary neutron star merger by LIGO/VIRGO and the associated electromagnetic counterpart provides a high precision test of orbital dyna…
