Joon-Bin Lee (SNU), "Parton Showers as a New Path to Light BSM Searches"

Wednesday 10 Jun 2026, 15:00 → 16:00 Asia/Seoul

CTPU Seminar room (Theory Bldg, 4F)

Traditional BSM searches focus on new particles produced directly in the hard process. However, light bosons may instead appear through soft or collinear radiation during parton-shower evolution. In this seminar, I will introduce the angular-ordered BSM parton shower implemented in Herwig 7 event generator, and then discuss its phenomenological application to Z′ radiation inside jets. Unlike conventional direct-production searches, shower-induced Z′ production can yield non-isolated dimuon signatures embedded in jets. This motivates a search strategy that is complementary to conventional direct-production searches, while also opening a potentially novel direction based on jet substructure and dimuon-jet correlations.
