Beyond Standard Model Physics under the ground and in the sky
<p>Cosmology and particle physics are in an exciting data-rich era, with several collider and astronomical searches underway. In this dissertation, we have explored some problems which are not addressed by the standard models of particle physics and cosmology. The implications of the Higgs …

Toward a Precision Measurement of CEvNS on Liquid Argon
… cross section will also allow probing important standard model and beyond standard model physics quantities, such as the weak nuclear radius of Ar40 , neutrino oscillation parameters, non standard neutrino interactions, and more. Progress on COH Ar 750 will be presented as well as studies …

Probing New Physics Through Third Generation Leptons
This dissertation is a study of beyond standard model physics or new physics. The third generation charged lepton -the τ -is an excellent probe of new physics (NP) because of it being the heaviest lepton. As the heaviest lepton, it has the largest coupling ( among the leptons) to the Higgs boson in …

Calorimetry at a Future Linear Collider
… couplings provide insight into possible beyond standard model physics. This study, which utilises the excellent jet energy resolution from Particle Flow Calorimetry, was performed at centre-of-mass energies of 1.4 TeV and 3 TeV with integrated luminosities of 1.5$\text{ab}^{-1}$ and …

Search for exotic Higgs boson decays to four leptons with the ATLAS detector
… decays are well motivated by various theoretical models, as well as the constraints from Higgs boson measurement results. The focus is on exotic Higgs boson decays to a pair of beyond-the-Standard-Model spin-0 particles $a$. This dissertation conducts two analyses for exotic Higgs bosons decaying …

Searching for signs of hidden sectors at the LHC: long-lived particle methods and models
Mysteries beyond the Standard Model (BSM) inspire theories, experiments and analysis tools that cover gaps in parameter space for new particles. Open questions ask the origins of neutrino masses, the mechanisms underlying flavour mass hierarchies, the matter-antimatter asymmetry and signs of dark …
