Here is a link for our virtual Sococo office https://app.sococo.com/meet/TheoryFukuKumar-2-3V5TZfWLZ1Z80412713 that will be active on Dec 16th. ——- I will give a general overview of experimental facilities with both high energies and high intensities, and how they can help explore dark matter models, complementary to astrophysical and cosmological searches. I will then talk about my new experimental proposals (FORMOSA, LongQuest, & … Read More

Abstract: If dark matter is a particle with a mass between the electroweak and Planck scale, we could detect it through its decays to high-energy cosmic rays. Testing this hypothesis requires a detailed understanding of the astrophysics of where these decays are occurring and the particle physics that dictates the spectra of produced cosmic rays. In this talk, I will describe … Read More

Axion-like particles may play a key role in early universe cosmology. They are naturally equipped with the right properties to explain cosmic inflation, can dynamically explain the smallness of the electroweak scale, may be involved in the generation of the matter antimatter asymmetry and are promising dark matter candidates. In this talk I discuss a generic but previously overlooked particle … Read More

Abstract: Well motivated models of dark matter such as inelastic dark matter and strongly interacting dark matter and other dark relics of stable particles are notoriously difficult to detect in direct detection experiments. This is due to their inability to impart large enough recoil energy in traditional methods of direct detection. In this talk, I propose a new paradigm for … Read More

Recent measurements by the Fermilab g-2 experiment seem to confirm the long-standing muon g-2 anomaly first measured by BNL. If theoretical and experimental progress in the coming years confirms the deviation from the Standard Model (SM) expectation, this would represent the first solid evidence of Beyond SM (BSM) physics. Over the years, many models have been proposed to account for … Read More

First-order phase transitions in the early universe could produce stochastic gravitational wave signals observable at future space-based observatories such as LISA; however, existing methods for predicting these signals are limited to weakly-coupled theories. In this talk, I present a new, nonperturbative formalism for false vacuum decay that integrates over local fluctuations in field space using the functional renormalization group. As … Read More
