DESCRIPTION:Speakers: Shayarneel Kundu\n\nThe most general massless partic
 le admitted by Lorentz Invariance and Quantum Mechanics is the “Continuo
 us Spin Particle” (CSP). A CSP has an infinite number of discretely spac
 ed helicity states which mix under the little group\, and hence under Lore
 ntz transformations. The magnitude of mixing is controlled by a new fundam
 ental parameter\, the spin-scale - $\\rho$. The free field theory\, its in
 teractions and preliminary phenomenology was introduced over the past deca
 de. The observables computed demonstrate a trend of recovering the physics
  similar to that of familiar massless particles at high energies\, with de
 viations at lower energies. In this talk\, I will talk about the leading o
 rder corrections to CSP mediated gravity\, and the interaction of a CSP wi
 th a spinning degree of freedom and some of its simple phenomenology\, not
 ing that in both cases\, the observables show a deviation from expectation
 s at low energies.\n\nhttps://indico.slac.stanford.edu/event/10512/
