SUMMARY:Probing Particle Physics with Gravitational Waves\, Theory Sem
 inar (High Energy/Cosmology)\, Horng Sheng Chia\, Institute for Advanc
 ed Study
DESCRIPTION:Gravitational wave astronomy will transform astrophysics i
 n many ways\; can it do the same for particle physics? In this talk\, 
 I will describe how the gravitational waves emitted by binary systems 
 offer us a new window onto physics beyond the Standard Model. I will f
 ocus on a specific class of new physics called ultralight bosons\, whi
 ch can spontaneously form boson clouds around rotating black holes. Re
 markably\, the dynamics of these clouds in binary systems can be formu
 lated as “scattering events” that are quantified by a “S-matrix�
 ��. Furthermore\, the signatures emitted by these binary systems allow
  us to infer the masses and intrinsic spins of these ultralight bosons
 \, making binary black holes novel detectors for these putative new fi
 elds. I will end with a brief discussion on probes of other types of n
 ew physics\, including current efforts to search for these novel signa
 tures in the data.
