Title
Searching for the Imprints of Heavy Particles at the LHC and CMB.
Abstract
After a long period of direct searches and explorations at the LHC, no
tantalizing evidence of new physics has been found. The null result opens up
various possibilities that a new particle is hidden in exotic places, or it is
much lighter and more weakly-coupled. Another potent possibility is that new
physics is at higher energy scale beyond what we can directly probe. This talk
seeks to unveil the imprints of new heavy particles in two orthogonal paths.
First, from the EFT point of view, new physics effects are encoded in
higher-dimensional operators that give rise to modifications in structure of
the SM couplings. Precision measurements of these couplings will provide a hint
at which scale new physics manifests itself. Second, we shine a new light on
the possibility that a new signature can show up on the CMB as localized
pairwise-hotspots due to heavy particle productions during the inflation. We
discuss a discovery potential of these heavy particles based on a wavelet
analysis and deep neural networks (DNN), beyond a conventional power spectrum
analysis.
