Abstract: I will discuss how the next generation of CMB and Large Scale Structure (LSS) experiments can uncover information about the primordial Universe. I will review the observational signatures of the initial conditions and explain how they are connected to the physics of Inflation. I will then highlight recent techniques that combine CMB and LSS measurements to probe velocity fields … Read More
Azadeh Maleknejad (CERN) “A new paradigm for particle cosmology” Abstract: Modern cosmology has been remarkably successful in describing the Universe from a second after the Big Bang until today. However, its physics before that time is still much less certain. It profoundly involves particle theory beyond the Standard Model to explain long-standing puzzles: the origin of the observed matter asymmetry, … Read More
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
I will discuss how to precisely compute the scattering rates of sub-GeV DM in dielectric targets, such as Si and Ge, accounting for collective effects such as screening etc.
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
