Anomalies in b to c u-bar q transitions remain puzzling as proposed new physics scenarios involving SU(2) doublets are not significantly relaxed by collider dilution or factorization breakdown.
Phenomenological analysis using NRQCD Green's functions and reweighting shows toponium signals may be detectable in single-leptonic final states with LHC Run 2 data.
In supersymmetric DFSZ axion models, the LHC with 140 fb^{-1} can probe axion decay constants below 10^{11} GeV for higgsino masses under 1 TeV via displaced neutralino decays to axino LSPs.
