A major focus of our group over the past decade has been the study of the continuum structure of p-rich light nuclei using the invariant-mass technique. This effort has led to the discovery of 7 new isotopes beyond (sometime well beyond) the proton drip line. Just as important are the finding of new resonances in previously known nuclei and parameter determination, or refinement, of resonances...

Dark matter may consist of feebly interacting massive particles (FIMPs) that have never thermalized with the cosmic plasma. Their relic density is successfully achieved through the freeze-in mechanism for a wide range of dark matter mass, significantly expanding the model space to be tested compared to other production mechanisms. However, testing the tiny couplings required by freeze-in is...

Dileptons are a crucial probe of the strongly interacting matter created in ultra-relativistic heavy-ion collisions. Leptons are produced during the whole evolution of the created matter and can traverse the medium with minimal interactions. Different kinematics of dilepton pairs (mass and transverse momentum ranges) can selectively probe the properties of the formed matter throughout its...
