Exploring interference between $P_{c\bar{c}}$ resonances and background in the pion-induced reaction

Qi-Fang Lü, Xurong Chen, Yu-Bing Dong +3

We present a phenomenological study of the near-threshold ${\pi }^{-}p\to J/\psi n$ reaction, focusing on the interference effects between the $s-$channel $P_{c\bar{c}}$ resonances and non-…
