 Search for new physics using events with two same-sign isolated leptons in the final state at CMS / Folgueras, Santiago (Oviedo U.) We present a search for new physics using events with two same-sign isolated leptons with/out the presence of b-jets in the final state, targetting two very different SUSY scenarios, one dominated by strong production of squarks and gluinos where the 3rd generation squarks are lighter than other squarks and the other dominated by electroweak production neglecting completely any strongly interacting particles.
