Modification of tensor force in \textit{p}-shell effective interaction

Kanhaiya Jha, Pawan Kumar, Shahariar Sarkar +1

In many shell model interactions, the tensor force monopole matrix elements often retain systematic trends originating in the bare tensor force. However, in the present work, we fi…

Role of individual components of two-nucleon interaction in nuclear matrix elements of $2 ν β β$ and $0 ν β β$ of $^{48}$ Ca: Beyond the closure approximation

Shahariar Sarkar, Pawan Kumar, Kanhaiya Jha +1

In the present work, we examine the role of central (C), spin-orbit (SO) and tensor (T) components of two-nucleon interaction in the nuclear matrix elements (NMEs) of the two-neutr…

Nuclear matrix elements for $λ$ mechanism of $0 ν β β$ of $^{48}$ Ca in nuclear shell-model: Closure versus nonclosure approach

Shahariar Sarkar, Y. Iwata, P. K. Raina

The $λ$ and $m_{β β}$ mechanisms of neutrinoless double beta decay ( $0 ν β β$ ) occur with light neutrino exchange via $W_{L} - W_{R}$ , and $W_{L} - W_{L}$ mediation, respectively. In the present s…
