Walls bounded by strings are a type of hybrid topological defect composed of cosmic strings and domain walls. Such a hybrid defect can appear when a $U(1)$ symmetry is broken into a $Z_n$ symmetry, which is further broken at a later time. The formation of walls affects the dynamic of the pre-existing string network and changes its gravitational wave radiation. We explore the relevant...
Beyond solving the hierarchy problem, classically conformal (CC) theories naturally accommodate dark matter (DM). In this work, we explore the CC $SU(2)_X$ gauge theory with a triplet dark scalar, uncovering three distinct DM scenarios: WIMP and supercooled DM. The production mechanisms are strongly influenced by the CC model's unique first-order phase transition evolution history, which...
The recent observation of CP violation in the decay Λb0→ pK-π+π by the LHCb
collaboration, with a significance of 5.2 standard deviations, presents a unique
opportunity to probe physics beyond the Standard Model. While the measured
asymmetry of (2.45 ± 0.46)% is consistent with some hadronic mechanisms within
the Standard Model, its resonant substructure and magnitude suggest...
