13. Charm Chromo-EDM as a Probe of Top-quark FCNC interactions

Electric dipole moments (EDMs) provide strong bounds on the CP structure of many New Physics (NP) scenarios. In this work, we study the charm Chromo-EDM (CEDM) within a new light scalar singlet with top-quark Flavour-Changing Neutral Current (FCNC) interactions. Such scalar singlet appears naturally in many well-motivated NP scenarios, such as the composite Higgs models. Unlike the Higgs boson...

CP violation in hadronic multi-body decays has been extensively studied, and the experimental breakthrough in the heayy baryon sector was made recently.
Partial-Wave CP Asymmetries (PWCPAs) in multi-body decays of heavy hadrons, which although provide us with more interference information, suffer from the
normalization problem, as is pointed out in this paper.
We propose a novel solution...

18. Progress of light hadron lightcone structures for heavy hadron decays on LQCD

The lattice QCD computation of parton distributions within the framework of large momentum effective theory (LaMET) constitutes a first-principles approach to studying hadron structures. Building upon preceding studies on meson systems, we have developed and partly implemented lattice methodologies for calculating the leading twist LCDAs of light baryons under the LaMET formalism over the past...
