**LQ searches**

//Project//: Studying single-production of third-generation LQ with tops and missing energy in the final state.

//Participants//: Giacomo Polesello, Priscilla Pani, David Marzocca, Dario Buttazzo

//To do//: Leptoquarks with charge 1/3 (or 2/3) can be singly produced in b-gluon with associated neutrino (tau) and decay to top and tau (neutrino). Study LHC sensitivity for such states.
Some relevant leptoquarks are: scalar S_1 (Q=1/3), scalar S_3 (components with Q=-2/3 or Q=1/3), vector U_1 (Q=2/3).
