Displaced searches for light vector bosons at Belle II

Journal of High Energy Physics, 2022
With a design luminosity of 50 ab −1 and detectors with tracking capabilities extending beyond 1 m, the Belle II experiment is the perfect laboratory for the search of particles that couple weakly to the Standard Model and have a characteristic decay ...

Resolving the muon g − 2 tension through Z′-induced modifications to σ had

Journal of High Energy Physics, 2023
The QED hadronic vacuum polarization function plays an important role in the determination of precision electroweak observables and of the anomalous magnetic moment of the muon.

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.

New Computational Techniques to Simulate Light Scattering from Arbitrary Particles [PDF]

Particle & Particle Systems Characterization, 1994
AbstractThe coupled dipole method, as originally formulated by Purcell and Pennypacker [3], is a very powerful method to simulate the elastic light scattering from arbitrary particles. This method, however, has one major drawback: if the size of the particles grows, or if scattering from an ensemble of randomly oriented particles has to be simulated ...

Shining New Light on the Kinetics of Water Uptake by Organic Aerosol Particles [PDF]

The Journal of Physical Chemistry A, 2021
The uptake of water vapor by various organic aerosols is important in a number of applications ranging from medical delivery of pharmaceutical aerosols to cloud formation in the atmosphere. The coefficient that describes the probability that the impinging gas-phase molecule sticks to the surface of interest is called the mass accommodation coefficient,

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

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.
