Pulsar timing arrays (PTAs) consisting of widely distributed and well-timed millisecond pulsars can serve as a galactic interferometer to detect gravitational waves. With the same data acquired for PTAs, we propose (https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.130.121401) to develop pulsar polarization arrays (PPAs), to explore astrophysics and fundamental physics. As in the case...

We would like to present our recent study of the four-body baryonic $B\to{\bf B_1\bar B'_1 B_2\bar B'_2}$ decay. We explain the branching fraction of $\bar B^0\to p\bar p p\bar p$ measured by LHCb as small as $2.2\times 10^{-8}$. We also predict the following branching fractions: ${\cal B}(B^-\to n\bar p p\bar p)=(8.4^{+2.1}_{-1.0}\pm 0.4^{+3.4}_{-1.9})\times 10^{-8}$, ${\cal B}(B^-\to...

Atomic nuclei lie at the core of everything we can see; and at the first level of approximation, their atomic weights are simply the sum of the masses of all the neutrons and protons (nucleons) they contain. Each nucleon has a mass mN ≈ 1 GeV, i.e. approximately 2000-times the electron mass. The Higgs boson - discovered at the large hadron collider in 2012 - produces the latter, but what...

Does the updated lepton non-universality parameter, given by LHCb in December 2022, imply that new physics in b to s window has faded way? In this work, we aim to answer this question by making global fits of Wilson coefficients in four different scenarios taking into account 196 observables in leptonic and semileptonic decays of B mesons and bottom baryons. We find that new physics...

In this presentation we would first introduce the basic idea of transversal momentum dependent ($k_T$) factorization theorem and its application in B meson decays, then we would show our recent calculation of charmless $B \to PP, PV, VV$ decay with including all the known next-to-leading-order QCD corrections, the $\pi K$ puzzle would also be mentioned.

Rare semi-leptonic decays of kaon and hyperon play an important role in testing the standard model of particle physics and searching for new physics. Based on the recent progresses from BESIII, NA48/2 and LHCb Collaboration, in this work we studied two kinds of semi-leptonic decays of kaon and hyperon, which are characterized as $s\to d\nu\bar{\nu}$ and $s\to d\mu^+\mu^-$ transitions at the...

With the large datasets on e^+ e^- annihilation at the J/ψ and ψ(3686) resonances collected at the BESIII experiment, multi-dimensional analyses making use of polarization and entanglement can shed new light on the production and decay properties hyperon-antihyperon pairs. In a series of recent studies performed at BESIII, significant transverse polarization of the (anti)hyperons has been...

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...
