Open charm mesons in variational scheme and HQET

K. K. Vishwakarma, Ritu Garg, Alka Upadhyay

The charm ( $D$ ) and charm-strange ( $D_{s}$ ) mesons are investigated in a variational scheme using Gaussian trial wave functions. The Hamiltonian contains Song and Lin potential with…

Sea quark-gluon effect on the magnetic octupole deformation of decuplet baryons

Preeti Bhall, Ritu Garg, Alka Upadhyay

The magnetic octupole moment of $J^{P} = \frac{3}{2}^{+}$ decuplet baryons are discussed in the statistical framework, treating baryons as an ensembles of quark-gluon Fock states. The p…

Sea-quark dynamics in decuplet ( $\frac{3}{2}^{+}$ ) $\to$ octet ( $\frac{1}{2}^{+}$ ) transition quadrupole moment

Preeti Bhall, Alka Upadhyay

We investigated the electromagnetic quadrupole transition of baryon decuplet ( $J^{P} = \frac{3}{2}^{+}$ ) to octet ( $J^{P} = \frac{1}{2}^{+}$ ) using the statistical framework together with th…
