In this talk I will focus on the tau -> pi pi gamma nu process. Special attention will be paid to the triple-product asymmetry arising from this decay channel. Anomalous rho-omega-pi type of interacting vertices, together with the ones with even parity, are simultaneously included in our calculation. The branching fraction of the radiative two-pion tau decay is predicted to be around 10^-4...
The $\tau$ lepton is the only known lepton massive enough to decay into hadrons. Besides serving as a clean laboratory for studying various low-energy aspects of the strong interactions, the hadronic $\tau$ decays may also allow us to explore CP-violating effects both within and beyond the SM. In this talk, I will discuss the CP asymmetries in $\tau \to K_S \pi \nu_\tau$ decays, which arise...
Semileptonic decays of charm-flavored hadrons, particularly D mesons, offer important avenues to address key questions in heavy-flavor physics, such as the long-standing discrepancy between inclusive and exclusive determinations of CKM matrix elements involving charm quarks. Precision measurements of semileptonic D-meson decays demand equally accurate theoretical predictions, for which QCD...
In this talk, I will present our recent follow-up lattice study building on our previous single-channel D\pi analysis (PRD 111, 014503 (2025)). In particular, I will discuss the two-pole structure of the D_0^*(2300) resonance.
The doubly charmed baryon, $\Xi_{cc}^{++}$, was first observed by
LHCb through the non-leptonic decay modes of $\Xi_{cc}^{++}\to\Lambda_{c}^{+}K^{-}\pi^{+}\pi^{+}$
and $\Xi_{c}^{+}\pi^{+}$. Following this discovery, researchers shifted
their focus to identifying other doubly charmed baryons, specifically
$\Xi_{cc}^{+}$ and $\Omega_{cc}^{+}$. In this study, we examine
the non-leptonic weak...
