Dark matter in the Randall-Sundrum model with non-universal coupling

Journal of High Energy Physics, 2019
We consider simplified dark matter models (DM) interacting gravitationally with the standard model (SM) particles in a Randall-Sundrum (RS) framework. In this framework, the DM particles interact through the exchange of spin-2 Kaluza-Klein (KK) gravitons

Defining Processing Times for Accelerator Produced ²²⁵Ac and Other Isotopes from Proton Irradiated Thorium

Molecules, 2019
During the purification of radioisotopes, decay periods or time dependent purification steps may be required to achieve a certain level of radiopurity in the final product.

On Generation, Motions, and Collisions of Dowsons

Frontiers in Physics, 2020
Dowsons are ±2π point singularities of the unitary complex order parameter eiφ characterizing the so-called dowser texture in a thin nematic layer with homeotropic boundary conditions.

Colliding poles with colliding nuclei

EPJ Web of Conferences, 2022
In these proceedings, I will discuss collisions of poles in the complex plane as a signature of phase transitions for theories relevant to the quark gluon plasma. I will begin with an illustrative example, namely the chiral phase transition, which can be characterized by colliding poles as a function of temperature.

Avoiding collider bias in Mendelian randomization when performing stratified analyses

European Journal of Epidemiology, 2022
Mendelian randomization (MR) uses genetic variants as instrumental variables to investigate the causal effect of a risk factor on an outcome. A collider is a variable influenced by two or more other variables.

Jet substructure at the Large Hadron Collider: A review of recent advances in theory and machine learning [PDF]

Physics reports, 2017
Jet substructure has emerged to play a central role at the Large Hadron Collider (LHC), where it has provided numerous innovative new ways to search for new physics and to probe the Standard Model in extreme regions of phase space.

Implications of CTEQ global analysis for collider observables [PDF]

, 2008
The latest CTEQ6.6 parton distributions, obtained by global analysis of hard-scattering data in the framework of general-mass perturbative QCD, are employed to study theoretical predictions and their uncertainties for significant processes at the ...
