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

Satoshi X. Nakamura

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

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…

Renormalization group analysis of the chiral pion production operator for NN\to dπ

Satoshi X. Nakamura, Anders Gardestig

We are interested in the consistency between the cutoff, chiral symmetry, and the power counting. For this purpose, we apply the Wilsonian renormalization group (RG) to an operator…
