Semi-inclusive electroproduction of hidden-charm and double-charm hadronic molecules | | Pan-Pan Shi

4 Aug 2022 | | Abstract: | The semi-inclusive electroproduction of exotic hadrons, including the
$T_{cc}$ states, $P_{cs}$ states, and hidden-charm baryon-antibaryon states, is
explored under the assumption that they are $S$-wave hadronic molecules of a
pair of charmed hadrons. We employ the Monte Carlo event generator Pythia to
produce the hadron pairs and then bind them together to form hadronic
molecules. With the use of such production mechanism, the semi-inclusive
electroproduction rates are estimated at the order-of-magnitude level. Our
results indicate that a larger number of $P_{cs}$ states and
$Lambda_car{Lambda}_c$ molecules can be produced at the proposed
electron-ion colliders in China and in the US, EicC and US-EIC, respectively.
The results also suggest that the $T_{cc}$ states and other hidden-charm
baryon-antibaryon states can be searched for at US-EIC. Besides, the potential
24 GeV upgrade of CEBAF at Jefferson Lab can play an important role in the
search of the hidden-charm tetraquark and pentaquark states due to its high
luminosity. | | Source: | arXiv, 2208.02639 | | Services: | Forum | Review | PDF | Favorites | |
