I will give an overview of pseudo-Dirac dark matter, a scenario where a small Majorana mass splits charged Dirac dark matter into two nearly degenerate states. A longtime favourite of model-builders, this dark matter candidate has a rich phenomenology that still has yet to be fully characterized. I will discuss a few mechanisms for producing this kind of dark matter in the early universe, and...

There is strong evidence for the existence of Dark Matter. One possible form of Dark Matter is strongly self-interacting Dark Matter, or Strongly Interacting Massive Particles (SIMP), modelled after Quantum Chromodynamics (QCD). It should also be noted that, to date, no direct detection of any kind of dark matter has been made. Direct detection of dark matter at accelerators is a high priority...

Many particle and rare-event search detectors use liquid scintillators as the detection method. A popular candidate for scintillation fluids are noble elements such as Liquid Argon (LAr). LAr detectors typically store their scintillators inside an acrylic vessel, which can be coated with various materials. A common coating is 1,1,4,4-tetraphenyl-1,3-butadiene (TPB) which is a wavelength...

The PICO collaboration aims to use superheated bubble chambers for the direct detection of dark matter, particularly in the spin-dependent WIMP-proton regime. PICO-40L is the current generation dark matter detector that is currently in the final stages of construction 2km underground at SNOLAB. It will be anticipating first commissioning results and early physics results early next year. The...

The NEWS-G experiment searches for low-mass dark matter candidates at SNOLAB in Sudbury, Ontario. The direct dark matter search is performed using a spherical proportional counter (SPC) filled with light atomic mass gases. NEWS-G3 is a proposed experiment that employs the same technology as the NEWS-G experiment to search for coherent elastic neutrino-nucleus scattering (CEνNS) at a nuclear...

Many important questions in Quantum Chromodynamics (QCD) remain unanswered, despite decades of investigation. For example, we cannot adequately explain how the fundamental properties (mass, spin) of objects such as the proton and neutron emerge from their constituent quarks and gluons. Interactions and structure in nuclear matter are intricately connected, the observed properties of composite...

The Electron-Ion Collider (EIC) is a new US$2 billion high-luminosity accelerator that is expected to be operational at Brookhaven National Laboratory, USA at the beginning of the next decade. One of the main goals of the EIC is to understand the origin of hadronic mass, this is the majority of visible mass (>99%) in the universe. From the little that we understand, we know that the mass of...

The Measurement Of a Lepton Lepton Electroweak Reaction (MOLLER) experiment anticipates new dynamics beyond the standard model. The measurements are acquired by the scattering of longitudinally polarized electrons off the unpolarized electrons using a set of detectors in Hall A at Thomas Jefferson National Accelerator Facility (JLab) in Newport News, Virginia USA. In the present...

The KaonLT/PionLT Collaboration probes hadron structure by measuring deep exclusive meson production reactions at Jefferson Lab. A set of high momentum, high resolution spectrometers in Hall C allow for precision measurements of cross sections at different kinematics, from which form factors and other observables can be extracted. One possible measurement from these reactions is the beam...

In perturbative QCD, processes involving quark scattering provide the simplest way of studying non-Abelian scattering amplitudes. To that end, in this talk I will discuss our calculation for the Form Factor of the Higgs boson production via light quark mediated Gluon Fusion process in the high energy/small quark mass limit, where the leading contribution comes in the form of large double...

Deep Inelastic Scattering (DIS) is described by an exchange of virtual photons or, at high energies, the $Z^0$. The distinctive characteristic of DIS in contrast to many processes (such as $pp$ at the LHC or $pA$ at the RHIC) is that the kinematics are precisely computable from the leptonic (and hadronic) final state at all orders. DIS reconstruction has a strong dependence on the collision...
