WIDG Seminar, Claire Laffan, Yale University, "Implementing Experimental Blinding on HAYSTAC"

Dark matter is one of the most intriguing problems in physics today, and axions have become a popular dark matter candidate in recent years. HAYSTAC is a quantum-enhanced dark matter experiment which uses novel techniques to search for axions. In this talk I will give an introduction to dark matter, axions, and the HAYSTAC experiment. Then I will discuss a blinding technique called “salting” and my progress with implementing a salting analysis on the HAYSTAC.

NPA Seminar, Fernando Flor, University of Houston, "Flavor, Energy and System Size Dependence of the Chemical Freeze-out in Relativistic Particle Collisions from RHIC-BES to LHC energies via Statistical Hadronization"

The validity of the Statistical Hadronization Model (SHM) has been successfully tested to adequately reproduce hadronic particle abundances over nine orders of magnitude in high energy collisions of heavy ions. Assuming a thermally equilibrated system, experimental particle yields at RHIC and the LHC serve as an anchor for the determination of common freeze-out parameters in the QCD phase diagram – namely, the baryo-chemical potential (µB) and the chemical freeze-out temperature (Tch) - via thermal fits in the SHM framework.

NPA Seminar, Daniel Pablos, INFN, "Deep Learning Jet Modifications in Heavy Ion Collisions"

High-energy jets experience severe modifications along their passage through the quark-gluon plasma (QGP), a new state of matter created in ultra-relativistic heavy ion collisions. Due to the steeply falling jet spectrum, when we measure jets we are typically looking at the jets that lost the least energy. This selection bias hinders our ability to study true jet modifications, resulting in a more limited knowledge of the way the QGP interacts with the energetic partons.

NPA Seminar, Lee McCuller, MIT, "Wielding the Quantum Correlations in advanced LIGO"

Optical interferometers have begun a new era of astrophysics by measuring vast lengths to such precision that gravitational waves from distant collisions of black holes and neutron stars are now regularly observed. This past run, the global gravitational wave network itself entered a new era, whereby every detector’s sensitivity is enhanced using quantum squeezed states of light. Manipulating profound measurement precision has profound consequences – measurement back action, in LIGO taking the form of quantum radiation pressure noise on 40kg mirrors.
