| الوصف: | A method to search for particles of unknown masses in final states with two invisible particles is presented. Searching for final states with missing energy is a challenging task usually performed in the tail of a missing energy related distribution. The search method proposed is based on a 2-Dimensional mass reconstruction of the final state with two invisible particles. Thus, a bump hunting is possible, allowing a stronger signal versus background discrimination. Parameters of the BSM theory can be extracted from the mass distributions, a valuable step towards understanding its true nature. The proof of principle of the method is based on the existing SM top pairs in their dilepton final state. Many interesting topologies including dark matter candidates or heavy top partners can be searched this way at the LHC. Comment: 9 pages, 16 figures |
