SUMMARY:Looking for new physics in rare and novel processes at the LHC
 \, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Saptaparna Bhattacharya
 \, Northwestern University
DESCRIPTION:The collection of a large dataset at the Large Hadron Coll
 ider (LHC) allows for the exploration of rare processes predicted by t
 he Standard Model of Particle Physics. In this talk I will focus on th
 e observation of triboson production with data collected by the CMS de
 tector at a center of mass energy of 13 TeV using the complete Run II 
 dataset. Triboson events are rare and feature novel topologies. I will
  provide a historical context for the first observation of tribosons a
 t the LHC and discuss prospects for this analysis as we head toward Ru
 n III and the high luminosity-LHC. Given the absence of any significan
 t sign of new physics at the LHC\, an effective field theory (EFT) app
 roach which posits that the source of new physics are heavy fields bey
 ond our current reach\, can be used to indirectly look for new physics
 . I will state how the newly observed triboson processes can be used a
 s a probe for new physics using the EFT framework. <br>
