Abstract: The discovery of the Higgs boson has completed the set of particles predicted by the Standard Model (SM). It has been established by the CMS and ATLAS Collaborations at the Large Hadron Collider that the discovered boson is consistent …
Abstract: As the universe cooled immediately following the Big Bang, the laws of physics underwent a dramatic phase transition. Underlying symmetries were broken and particles acquired mass as the Higgs field moved to a new ground state. In this talk …

Abstract: During Run 1 of LHC, the ATLAS and CMS collaboration firmly established the existence of a Higgs boson but detailed measurements were limited by statistical precision. With the larger Run 2 dataset, we have measured the couplings and production …
Abstract: Dark matter represents one of the most sought after discoveries in physics. Leading theories predict that extremely sensitive detectors could probe nuclear recoils from dark matter interactions. The PICO collaboration uses bubble chambers to look for the energy deposition …
Abstract: “Despite the huge success of the Standard Model (SM), there is overwhelming evidence for physics beyond the SM and many remaining questions, such as the nature of dark matter (DM). The current leading candidate for DM are Weakly Interacting …
Abstract During Long Shutdown 3 (2024/2025) of the Large Hadron Collider, the ATLAS Inner Detector will be replaced with a new all-silicon tracker, composed of a pixel and a strip tracker. The strip tracker will consist of 18,000 detector modules, …

Abstract: Ultra-high-energy (> 10^18 eV) neutrinos remain undiscovered in this era of rapid growth in multi-messenger astronomy. These neutral and weakly-interacting particles can travel cosmic distances without attenuation and point straight back to their source, rendering them promising messengers. Detection …
Abstract: Despite the tremendous success of the Standard Model (SM) of particle physics, it becomes more and more clear that the SM is far from complete. For example, the non-zero neutrino mass was the first solid evidence beyond the SM, …
ABSTRACT: Cosmology in the next decade will be driven by data. Exploiting the information one can extract from the ongoing and upcoming large surveys will give us the power to stress-test the LCDM model with unprecedented precision and open up windows …
ABSTRACT: I will discuss motivations for searching for di-Higgs production at the LHC. Recent results and projected sensitivities will be presented with emphasis on the dominant hh->4b channel.
