Experimental particle physics; physics beyond the standard model; weak interactions
Our model of elementary particles describes a panoply of experimental results, and predicts a Higgs boson that may be the boson that was recently discovered at the LHC. However the Standard Model falls short of explaining other phenomena such as dark matter, the disappearance of anti-matter from the universe, and the small size of the radiative corrections to the Higgs mass. My research uses data from the Large Hadron Collider (LHC), which now collides protons with center-of-mass energies of 8 TeV, to seek the new phenomena and particles that may explain these mysteries. My student Avishek Chatterjee has recently completed a search for supersymmetry in events with electrons or muons and large missing energy. Like other searches for SUSY at the LHC, he sees no hint of a signal so far. Most SUSY searches to date at the LHC have made assumptions about SUSY, some of them poorly justified. Inspired by the work of Cornell’s theory group, I am now starting a project to look for SUSY without assuming that SUSY-number (R-parity). This project has openings for new students.
