This workshop introduces parallel programming concepts and demonstrates their implementation with Python. We will discuss parallel concepts, classes of parallel programs, Python’s implementation of parallel workflows, and showcase several toolkits for CPU and GPU-based parallel programming in Python. Additionally, we will discuss leveraging cluster-infrastructure for large parallel work via Slurm Job Arrays.
This prospectus carries the goal of testing the DAMA/LIBRA (DL) dark matter claim by combining two collaborations who have set forth to reproduce the DL annual modulation signature, COSINE-100 and ANAIS-112. COSINE-100’s recent modulation results support both the no modulation case and the DL modulation case. ANAIS- 112 excludes DL to 2σ. A combination of the two experiments would allow for a sensitive search from opposite sides of the world, notably, Spain and Korea.
Well-defined operators which are capable of describing measurements made at future null infinity in collider experiments are naturally of phenomenological interest, but they are also of great formal interest. Here we discuss the properties of these so called asymptotic detector operators, including both their formal construction in terms of light-ray operators in a conformal field theory, as well as their utility in jet substructure phenomenology.

At extremely high temperature and energy density, the quarks and gluons form a novel state of matter called the Quark-Gluon Plasma (QGP). The QGP has been widely studied via relativistic heavy ion collisions in large collision systems like Au+Au and Pb+Pb. However, whether the QGP exists in small systems like p+Au, and the dependence of QGP production on the collision system size are still open questions. One way to study the QGP properties is by using proxies of high energy partons, which are created in the initial stages of the collisions, and fragment into hadrons in the final state.
While dark matter accounts for approximately 85% of the mass in the universe, its physical nature remains one of the most pressing open questions in the field of physics. Three decades of experiments have been searching for dark matter interactions over a wide range of candidate dark matter masses and all have come up empty-handed. Nevertheless, there remain large swaths of unexplored, well-motivated particle dark matter models that are currently inaccessible through existing detector technologies.
I will present the crystalline xenon time projection chamber (TPC), a promising novel technology for next-generation dark matter searches. Initial tests have established that it maintains many of the benefits of the liquid xenon TPC while also effectively excluding radon, the dominant background in currently-running xenon dark matter experiments such as LZ. This offers the potential for greatly improved sensitivity to dark matter through a crystal xenon upgrade to an existing experiment.
As the gravitational evidence accumulates inexorably that dark matter comprises the vast majority of the mass of the universe, the particle nature of dark matter remains a mystery. New laboratory experiments are being commissioned to probe sub-GeV dark matter, but the signatures in these detectors rely crucially on the condensed matter properties of the detector material. Similarly, detecting the couplings of axions to matter requires considering collective modes in materials.
One of the main goals of the Beam Energy Scan (BES) program at the Relativistic Heavy-Ion Collider (RHIC) is to detect signatures of the conjectured QCD critical point. A prediction based on universality arguments suggested that non-monotonic behavior in the fourth-order baryon susceptibility (chi-4) is a critical signature. The net-proton kurtosis, as a function of beam energy, is thought to be a good experimental proxy for chi-4. This discussion became even more relevant after results from the first run of the BES program showed hints of non-monotonic behavior in the net-proton kurtosis.
The internal structure (substructure) of jets produced in high-energy hadron collisions encodes rich Quantum Chromodynamics (QCD) dynamics, from the interaction of quarks and gluons in the weakly coupled limit to the hadronization process in the strongly coupled limit. Studies on jet substructures have attracted interest from both the theoretical and experimental sides, together advancing our understanding of QCD. Central to the recent development of jet substructure has been the use of energy correlators, which measure statistical correlations of the energy flux within a jet.
