SUMMARY:On the Topic of Jets - Jesse Thaler (MIT)
DTSTART:20180501T153000Z

UID:TALK104992@talks.cam.ac.uk
CONTACT:Benjamin Christopher Allanach
DESCRIPTION:When quarks and gluons are produced in high-energy collisions\
 , their fragmentation and hadronization via QCD results in collimated spra
 ys of particles called jets.  While quark and gluon partons carry color ch
 arge\, jets are composed of color-singlet hadrons\, so there is no unambig
 uous definition of "quark" and "gluon" at the hadron level.  Remarkably\, 
 a similar kind of problem is faced when analyzing the distribution of word
 s in a set of documents\, and there is a framework called "topic modeling"
  to identify emergent themes in a corpus without having to specify those t
 hemes a priori.  In this talk\, I present preliminary studies applying top
 ic modeling to jet physics\, and I speculate on a possible application of 
 jet topics to extract the strong coupling constant.
