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.

A large amount of data on hadronic two-body weak decays of antitriplet charmed baryons $T_{c\bar{3}}$ to an octet baryon $T_8$ and an octet or singlet pseudoscalar meson $P$, $T_{c\bar{3}} → T_8P$, have been measured. The SU(3) flavor symmetry has been applied to study these decays to obtain insights about weak interactions for charm physics. Combined with known data on decay, much information...

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...
