Exclusive radiative production of fully-charmed tetraquarks at B factory
We apply a novel factorization formula recently developed within NRQCD framework to analyze the exclusive production of the fully-charmed tetraquark T4c plus a hard photon at super B factory. For simplicity, in this work we have concentrated on the production of the 0++ and 2++ T4c associated with a...

| Summary: | We apply a novel factorization formula recently developed within NRQCD framework to analyze the exclusive production of the fully-charmed tetraquark T4c plus a hard photon at super B factory. For simplicity, in this work we have concentrated on the production of the 0++ and 2++ T4c associated with a photon. With some rough estimates about the unknown nonperturbative NRQCD matrix elements in a simplified diquark-antidiquark model, we predict the production rates of these types of exclusive production channels at s=10.58 GeV and also assess their observation prospect at Belle 2 experiment. |
