Strong decays and effective spin-symmetry-breaking corrections in excited charm-strange mesons

Xiao Yu, Chao-Qiang Geng

We study two-body pseudoscalar-emission decays of excited charm-strange mesons in heavy meson effective field theory, where phenomenological $1/m_c$ corrections are encoded as ef…

Potential of discovering $I^_{cc}^{+}$ in $I^_{b}$ decays

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu +2

We propose to search for $I^_{cc}^{+}$ in the decay $I^_{b} \to I^_{cc}^{+} D^{-}$ , which serves as a tagged and reconstructible source of $I^_{cc}^{+}$ , providing an experimentally clean en…

Hidden strangeness in meson weak decays to baryon pair

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu +1

Our study focuses on the weak decay of $D_{s}^{+} \to p n$ , which is the only possible two-body baryonic decay in the $D$ meson system. An analysis using perturbative qu…
