Axial vectors in DarkCast

Journal of High Energy Physics, 2022
In this work, we explore new spin-1 states with axial couplings to the standard model fermions. We develop a data-driven method to estimate their hadronic decay rates based on data from τ decays and using SU(3)flavor symmetry.

Terrestrial detection of hidden vectors produced by solar nuclear reactions

Journal of High Energy Physics, 2023
Solar nuclear reactions can occasionally produce sub-MeV elusive beyond the Standard Model particles that escape the solar interior without further interactions. This study focuses on massive spin-one particles.

Probing light mediators and (g − 2) μ through detection of coherent elastic neutrino nucleus scattering at COHERENT

Journal of High Energy Physics, 2022
We present the constraints on the parameters of several light boson mediator models obtained from the analysis of the current data of the COHERENT CEνNS experiment. We consider a variety of vector boson mediator models: the so-called universal, the B − L

Quantum Disentangled Liquids [PDF]

, 2013
We propose and explore a new finite temperature phase of translationally invariant multi-component liquids which we call a "Quantum Disentangled Liquid" (QDL) phase.

FCNC charmed-hadron decays with invisible singlet particles in light of recent data

Journal of High Energy Physics, 2023
The flavor-changing neutral current (FCNC) decays of charmed hadrons with missing energy (Ɇ) can serve as potentially promising hunting grounds for hints of new physics, as the standard-model backgrounds are very suppressed.

FCNC B and K meson decays with light bosonic Dark Matter

Journal of High Energy Physics, 2023
We consider decays of B and K mesons into a pseudo-scalar or vector meson plus missing energy. Within the SM, these modes originate from flavor changing neutral current (FCNC) processes with two neutrinos in the final state. In this paper we consider the

Search for Light New Physics at B Factories [PDF]

, 2012
Many extensions of the Standard Model include the possibility of light new particles, such as light Higgs bosons or dark matter candidates. These scenarios can be probed using the large datasets collected by B factories, complementing measurements ...

Higgs squared

Journal of High Energy Physics, 2023
We present a novel construction for a Higgs-VEV sensitive (HVS) operator, which can be used as a trigger operator in cosmic selection models for the electroweak hierarchy problem.

Searches for light new physics at BABAR [PDF]

, 2012
B-factories are ideal machines to probe for light New Physics, thanks to their high luminosities and low background environments. In the following, we report recent searches for a light Higgs boson, lepton universality violation and dark matter ...

Physics at the Light-Front [PDF]

, 2001
The light-front representation of quantum chromodynamics provides a frame-independent, quantum-mechanical representation of hadrons at the amplitude level, capable of encoding their multi-quark, hidden-color and gluon momentum, helicity, and flavor ...
