87. The Cosmology and Astrophysics of Dark Complexity

Physics Beyond the Standard Model

Invited Oral

Simple hidden sector theories can give rise to interacting dark matter involving multiple particle species and long-range interactions, such as atomic dark matter. These scenarios are highly plausible in their own right, but can be particularly motivated by modern solutions to the Hierarchy Problem such as the Twin Higgs. These dark matter models feature dissipative dynamics and bound state...

37. An Auxiliary ATLAS Detector to Enhance the Detection of Long Lived Particles

Physics Beyond the Standard Model

Contributed Oral

Several models that provide solutions to the Standard Model's open problems allow for the possibility of long lived particles (LLPs) with lifetimes, in some cases, in excess of $10^{3}$ seconds. It is proposed that charged LLPs produced at the Large Hadron Collider could interact with the ATLAS detector, eventually coming to rest and decaying. Other LLPs, such as neutral particles, may also...

18. Searches for periodic resonance signals in the $e^+e^-$ and $\gamma\gamma$ channels at $\sqrt{s}=13$ TeV in ATLAS

Physics Beyond the Standard Model

Contributed Oral

We analyzed diphoton($e^+e^-$) and dielectron($\gamma\gamma$) invariant mass spectrums in ATLAS to search for periodic resonance signals which are the decay products of clockwork gravitons predicted by the clockwork model. The clockwork model attempts to answer the hierarchy problem through a novel particle-generating mechanism. The name clockwork follows from the mechanics of obtaining a...

66. Background simulations on Charged-Lepton Flavour Violation (CLFV) in the Leptoquark framework at the EIC

Physics Beyond the Standard Model

Contributed Oral

The discovery of neutrino oscillations provided evidence of lepton flavour vi- olation. In this work, we carry out the background simulations in the leptoquark framework. Leptoquarks are bosons which carry lepton and baryon numbers, coupling leptons to quarks and mediating charged lepton flavour violation pro- cesses at tree-level. The goal of this work is to study charged lepton flavour...

17. Signal corrections using background detectors in MOLLER experiment

Ms Fatemeh Gorgannejad (University of Manitoba)

2023-02-16, 8:30 p.m.

Physics Beyond the Standard Model

Contributed Oral

Distinguishing between signal events and background events is the main issue in the integrating measurments of nuclear physics and particle physics experiments. Signal corrections can be accomplished either theoretically or experimentally. In the experimental approaches, a set of detectors called background detectors is implemented. In background detectors, the majority of particles generating...

28. Compton Polarimetry at the Electron-Ion Collider

Akshaya Vijay (University Of Manitoba)

Particle Physics

Contributed Oral

The US-based future Electron-Ion Collider is a novel tool to address some of the unexplained physics of nucleons, including how their constituents contribute to their properties like spin, mass, etc., by colliding highly polarized electron beams with polarized beams of protons or ions. The high-energy interactions between the electrons and protons help in understanding the internal structure...
