Secluded dark matter in gauged B ? L model

We consider the gauged $B-L$ model which is extended with a secluded dark sector, comprising of two sector particles. In this framework lightest $\mathcal{Z}_2$-odd particle matter candidate, having feeble interaction all other SM and BSM states. The next-to-lightest in super-wimp, large strength analyse relevant production processes that contribute to relic abundance, broadly classify them different scenarios, a) primarily produced via non-thermal process, b) mostly from late decay particle. discuss dependency abundance on various parameters. Furthermore, we also discovery prospect Higgs invisible searches.
