Undergraduate Researcher Nicole Khusid featured in UConn Today
Physics major Nicole Khusid, a rising senior at UConn, was featured in a UConn Today article about her research. Nicole has been working on gravitional lensing of distant sources of gravitational waves, seeking to understand their multimessenger signals and detectability by future astrophysics facilities. Nicole was awarded a SURF (Summer Undergraduate Research Fund) award to […]

Standard model challenged by new measurement
It seems that the muon, a heavier partner of the electron, may be breaking what have been understood as the laws of physics. The findings announced on April 7th were met with excitement and speculation at what this might mean. UConn physics researchers Professor Thomas Blum and Assistant Professor Luchang Jin helped pioneer the theoretical physics behind the findings.

The CAMELS Project: Cosmology and Astrophysics with MachinE Learning Simulations
In this talk, I will present the Cosmology and Astrophysics with MachinE Learning Simulations --CAMELS-- project, whose main goal is to provide theoretical predictions for cosmological observables as a function of cosmology and astrophysics. CAMELS contains a collection of 4,233 cosmological simulations, 2,049 N-body simulations and 2,184 state-of-the-art (magneto-)hydrodynamic simulations employing three different codes: Gadget-III, AREPO, and GIZMO. The simulations, designed to train machine learning models, span a very wide range in the value of the cosmological and astrophysical parameters. I will illustrate the potential of CAMELS by showing a few examples of tasks that we have carried out, such as teaching neural networks to extract cosmological information and marginalize over baryonic effects at the field level, finding a new universal relation between subhalo/galaxy properties, inferring the mass of a dark matter halo from the positions and properties of its galaxies, using neural networks to reconstruct masked data, doing cosmology with one single galaxy, and teaching neural networks to learn about cosmology and astrophysics with fast radio bursts. I will conclude by discussing how CAMELS will escalate in the coming years to generate millions of hydrodynamic simulations covering gigaparsec volumes for thousands of different cosmological and astrophysical models that will be used to extract the maximum cosmological information from upcoming cosmic surveys across the entire wavelength spectrum.Contact Information: Prof. Daniel Angles-Alcazar

Radiative corrections in Kaon semileptonic decays and the Cabibbo angle anomaly
In recent years we observe a series of mutually inconsistent determinations of the Cabibbo angle which is responsible for the mixing between the up and down quark. These anomalies, that occur in various beta decay experiments, are at the level of 3 sigma and provide strong evidence of the deviation from precise Standard Model (SM) predictions. To sharpen them to a level sufficient to declare a discovery, we must improve the theory precision of all the precise SM inputs to these decay processes. In this talk I describe recent progress along this direction: A new high-precision calculation of the electroweak radiative corrections in Kaon semileptonic decays is
performed. It features a chiral resummation of the large
infrared-singular terms in the radiative corrections and a
well-under-control strong interaction uncertainty based on the most recent lattice QCD inputs (by UConn physicists and collaborators). While being consistent with the previous state-of-the-art results obtained from chiral perturbation theory, we reduce the existing theory uncertainty from \(10^{-3}\) to \(10^{-4}\). Our result suggests that the SM electroweak effects cannot account for the anomaly in the Vus sector.Contact Information: Prof. Luchang Jin
