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.
Recursive Jigsaw Reconstruction is applied to reconstruct toponium at the ttbar threshold, with two variables proposed to improve signal sensitivity.
