ABSTRACT: The Higgs boson is expected to decay to bb approximately 58% of the time. Despite the large branching fraction, due to the large background from SM events with b-jets, measuring this decay has been less precise than other, less …
Abstract: Searching for new physics beyond the standard model (BSM) has been one of the main goals of the LHC. With no new physics found in many SUSY and Exotica searches for prompt BSM particles from the LHC data, I …

ABSTRACT: Quantum information science in the coming decade will likely be carried out on noisy devices consisting of ~100-1000 qubits that do not share full interconnectivity. In this so-called NISQ regime, variational quantum algorithms, which tackle a wide range of …
Abstract: I will talk about quantum simulation algorithms based on the light-front formulation of quantum field theory. They will range from ab initio simulations with nearly optimal resource scalings to VQE-inspired methods available for existing devices.My work is greatly inspired …
Abstract: Noble liquid detectors, especially liquid argon and liquid xenon time projection chambers (TPCs) have been developed and improved during the last decades. They produced the best limits in the search for one of the best motivated dark matter candidates, …
Abstract: The most sensitive searches for dark matter (DM) with mass above ~10 GeV/c2 use the dual-phase xenon time-projection chamber (LXe-TPC) technology. In the U.S., development of this technology is spearheaded by the LUX-ZEPLIN experiment, with first science data coming …
- Abstract: In order to infer cosmological parameters from data of upcoming surveys like DESI, we will use summary statistics such as the power spectrum. An accurate estimate of their covariance matrix is crucial for the inference analysis. The traditional process …
Abstract: What is the nature of dark matter? What leads to the fundamental forces having such disparate strengths? Can we explain the small mass of the Higgs boson without excessive fine tuning? These outstanding questions are part of a broad …
Abstract: The talk will present my PhD project research which focuses on advancing the standardization of various transients to be used as cosmological probes and the evaluation of the Hubble constant (H0). With SN Ia, I will present interesting results …

Abstract: Modeling galaxy-dark matter connection is essential in deriving unbiased cosmological constraints from galaxy clustering observations. We show that a more physically motivated galaxy-dark matter incorporating secondary biases can result in more accurate predictions of galaxy clustering, and that it …
