Decipher the short-distance component of $X (3872)$ in $B_{c}$ decays

Wei Wang, Qiang Zhao

A foremost task in understanding the nature of the $X (3872)$ involves the discrimination of the two-quark and multiquark configurations. In this work, we propose a method to probe…

$a_{1} (1260), a_{1} (1420)$ and the production in heavy meson decays

Wei Wang, Zhen-Xing Zhao

The $a_{1} (1420)$ with $I^{G} (J^{P C}) = 1^{-} (1^{++})$ observed in the $π^{+} f_{0} (980)$ final state in the $π^{-} p \to π^{+} π^{-} π^{-} p$ process by the COMPASS collaboration seems unlikely to be an…

Chiral Dynamics and S-wave contributions in Semileptonic $D_{s} / B_{s}$ decays into $π^{+} π^{-}$

Yu-Ji Shi, Wei Wang

In this work, we study the semileptonic decay modes $B_{s}^{0} \to π^{+} π^{-} ℓ^{+} ℓ^{-}$ and $D_{s}^{+} \to π^{+} π^{-} ℓ^{+} ν$ in the kinematics region where the $π^{+} π^{-}$ system has a invariant m…

How to reveal the exotic nature of the P_c(4450)

Feng-Kun Guo, Ulf-G. Meißner, Wei Wang +1

The LHCb Collaboration announced two pentaquark-like structures in the $J / ψ p$ invariant mass distribution. We show that the current information on the narrow structure at 4.45 GeV…

To understand the rare decay $B_{s} \to π^{+} π^{-} ℓ^{+} ℓ^{-}$

Wei Wang, Rui-Lin Zhu

Motivated by the LHCb measurement, we analyze the $B_{s} \to π^{+} π^{-} ℓ^{+} ℓ^{-}$ decay in the kinematics region where the pion pairs have invariant mass in the range $0.5$ - $1.3$ GeV a…

Radiative Leptonic $B_{c} \to γ ℓ ν ˉ$ Decay in Effective Field Theory beyond Leading Order

Wei Wang, Rui-Lin Zhu

We study the radiative leptonic $B_{c} \to γ ℓ ν ˉ$ decays in the nonrelativistic QCD effective field theory, and consider a fast-moving photon. As a result the interactions with t…
