Two nearby states in the $X (3872)$ region: Resolving the radiative-decay ratio tension with $I^\cdot_{c 2}$

Satoshi X. Nakamura

Recently, LHCb reported the radiative-decay ratio $R^{I ¨ I^^{3}} \equiv B [X (3872) \to I ¨ ^{'} I^^{3}] / B [X (3872) \to J / I ¨ I^^{3}] = 1.67 \pm 0.25$ extracted from $B^+\to K^+(J/ÏÎ³, Ï'…

Coupled-channel analysis for vector charmonia and their nature

Satoshi X. Nakamura

High-precision $e^{+} e^{-} \to c c ˉ$ data (20 final states) from the BESIII and Belle in $s = 3.75 - 4.7$ GeV are analyzed with a semi three-body unitary coupled-channel model. V…
