Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. This possibility could arise in a simple model in which a dark photon ( A 0 ) is light enough to generate an attractive force between dark fermions. We report herein a search for a J PC ¼ 1…

Neutrino phenomenology, muon and electron (g-2) under $U(1)$ gauged symmetries in an extended inverse seesaw model

The proposed work is an extension of the Standard Model, where we have introduced two anomaly free gauge symmetries i.e. U(1)B−L and U(1)Le−Lμ in an inverse seesaw framework. For this purpose, we

We measure the B0 − B0 mixing frequency ∆md using ∼ 6000 B0 → D−(K+π−π−)π+ candidates from 36 pb−1 of data taken in physics runs of the LHCb experiment in 2010. We use opposite and same side tagging
