Exclusive radiative production of fully-charmed tetraquarks at B Factory
Abstract
We apply the newly developed NRQCD factorization formula to analyze the exclusive production of the fully-charmed tetraquark T4c plus a hard photon at B factory. For simplicity, in this work we have concentrated on the associated production of the 0++ and 2++ tetraquarks with a photon. With some rough estimates about the size of the unknown nonperturbative NRQCD matrix elements, we predict the production rates of these types of exclusive channels at s=10.6 GeV and also assess their observation prospect at Belle 2 experiment.
