Top quark FCNC in Randall-Sundrum models: post-LHC allowed rates and searches at $e^{+} e^{-}$ and $I^¼^{+} I^¼^{-}$ colliders

Sagar Airen, Roberto Franceschini

We present the sensitivity to Flavor Changing Neutral Currents (FCNC) in interactions involving the top quark at future $e^{+} e^{-}$ and $I^¼^{+} I^¼^{-}$ machines. We consider the $Z t c$ vert…

Searching for Hidden Sector Particles at Neutrino Telescopes

Sagar Airen, Zackaria Chacko, Can Kilic +1

We explore the possibility of directly detecting light, long-lived hidden sector particles at the IceCube neutrino telescope. Such particles frequently arise in non-minimal hidden…

Vector Portals at Future Lepton Colliders

Sagar Airen, Edward Broadberry, Gustavo Marques-Tavares +1

We assess the sensitivity of future lepton colliders to weakly coupled vector dark portals (aka `` $Z^{'}$ bosons'') with masses ranging from tens of GeV to a few TeV. Our analysis f…
