Masses and Magnetic Moments of Singly Heavy Pentaquarks
arxiv(2024)
摘要
Motivated by the recent discovery of single heavy tetraquark structures,
T_cs̅0^a (2900)^++ and T_cs̅0^a(2900)^0 by the LHCb
collaboration, masses and magnetic moments of singly heavy pentaquark states
are estimated in this work. To classify the singly heavy pentaquark structures,
we employ the special unitary representation. By using the SU(3) flavor
representation, we placed singly heavy pentaquark states into the allowed
flavor multiples. Also, by using the extension of the Gursey-Radicati mass
formula and the effective mass scheme, we estimated the masses of singly heavy
pentaquark states. Further, magnetic moments of these states have been
calculated using the effective mass and the screened charge techniques. A
thorough comparison of our results shows reasonable agreement with the
available theoretical data and may be helpful for future experimental studies.
