Stellar explosions such as novae, supernovae, X-ray bursts, and neutron star mergers are responsible for the synthesis of a large fraction of the terrestrial elements. Nucleosynthesis in explosive environments is driven by rapid successions of nuclear reactions and decays.

Superradiant axions around black holes can produce electromagnetic signatures via lasing or via conversion to photons in a strong magnetic field. The latter can also produce gravitational wave signatures besides electromagnetic ones in binary merger events involving a strongly magnetized neutron star and a black hole (BHNS). Due to the smallness of the axion mass, medium effects of the black...

Flavor SU(3) analysis of B meson charmless hadronic two light pseudoscalar decays can be formulated in two different ways.

We first point out that previous analyses of TDA and IRA approaches do not match...

Since the pioneering study by Matsui and Satz on $J/\psi$ suppression by quark-gluon plasma formation in relativistic heavy ion collisions, there have been a large number of theoretical and experimental studies on this topic. These studies have significantly enhanced our understanding of the properties of $J/psi$, its excited states, and other quarkonium states consisting of bottom quarks at...

It is well known that protons and neutrons are made from constituents, called quarks and gluons, which give substructure to these particles. The goal of this project is to make measurements of the spatial distributions and the momenta of the quarks that provide a three-dimensional map of quarks in the nuclear medium. This knowledge provides the basis of our understanding of nuclear matter in...

With the continuing discrepancy in experimental measurements of the proton radius, $\textit{ab initio}$ determination of this quantity from QCD is urgently needed. At present, QCD calculations on a lattice are performed with physical values of light and strange quarks and adequate lattice volumes to permit credible control of systematic errors. One particular obstacle to computing the nucleon...

After an introduction to machine learning from the perspective of a theoretical physicist, I will describe a new method to perform a model independent search for new phenomena, with an emphasis on the LHC. I will discuss a systematic way to address the look-elsewhere effect and other issues that led similar attempts to fail in the past.

Purely hadronic weak interactions inside a nucleus produce a toroidal current distribution around the axis of nuclear spin. This distribution, known as the nuclear anapole moment, produces a local magnetic field that couples to the spin of a penetrating electron. This in turn gives rise to a nuclear spin-dependent parity-violating (NSD-PV) electron-nucleus interaction. We study NSD-PV effects...

sPHENIX is a large-acceptance, high-rate jet and $\Upsilon$ detector designed to study the structure of the quark-gluon plasma in heavy ion collisions at RHIC. It consists of full calorimeter over the full azimuth for $|\eta|<1.1$ with tracking and precision vertexing. These components will provide full jet reconstruction, heavy-flavor jet tagging, and $\Upsilon$ spectroscopy. We will...

Semi-inclusive deep inelastic Scattering (SIDIS) has been a very successful tool to investigate the partonic structure of the nucleon over the last decade. Compared to inclusive DIS, information about the quantum numbers of the struck quark can be inferred from the identity, distribution and polarization of the final state hadrons. Up to now, virtually all knowledge about the quark-gluon...

We present a new method for calculating the nucleon electromagnetic form factors (EM FFs) combining Chiral Effective Field Theory (ChEFT) and dispersion analysis [1]. The FFs are expressed as dispersive integrals over the two-pion cut at timelike $t > 4 M_\pi^2$. The spectral functions are computed using elastic unitarity, chiral pion-nucleon amplitudes (LO, NLO, partial N2LO), and timelike...

The exploration of the QCD phase diagram has been one of the main drivers of contemporary nuclear physics. The Relativistic Heavy Ion Collider (RHIC) at BNL is uniquely suited for this task through its Beam Energy Scan (BES) program which allowed for a large range in baryon chemical potential $\mu_B$ as was successfully demonstrated after the completion of Phase 1 in 2014. Phase 2 of the BES...
