Masses and Magnetic Moments of Singly Heavy Pentaquarks

Abstract

Motivated by the recent discovery of single heavy tetraquark structures, $T_{c\bar{s}0}^a(2900{)}^{++}$ and $T_{c\bar{s}0}^a(2900{)}^0$ 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.
