Abstract:Abstract. The XENON Dark Matter Experiment has been ongoing at LNGS since 2005 with the goal of searching for dark matter WIMPs with liquid xenon as target and detector material. With detectors of increasing target mass and decreasing background, the XENON program has achieved competitive limits on WIMP-nucleon interaction couplings, but also on axions and axion like particles. With the start of the next generation experiment, XENON1T expected in 2015, XENON Dark Matter Experiment will continue to lead field o… Show more
“…Moreover, we put our finding into perspective with dark matter endeavors in light of ongoing and next generation of direct detection experiments, namely XENONnT, LZ, and Dar- win [10][11][12][13][14][15][16] 3 . Since both collider and direct dark matter detection observables are dictated by the Z interactions an interesting degree of complementarity between these searches is expected [23][24][25][26][27][28][29][30][31][32] as we discuss further on.…”
Grand Unified Theories (GUT) offer an elegant and unified description of electromagnetic, weak and strong interactions at high energy scales. A phenomenological and exciting possibility to grasp GUT is to search for TeV scale observables arising from Abelian groups embedded in GUT constructions. That said, we use dilepton data (ee and µµ) that has been proven to be a golden channel for a wide variety of new phenomena expected in theories beyond the Standard Model to probe GUT-inspired models. Since heavy dilepton resonances feature high signal selection efficiencies and relatively well-understood backgrounds, stringent and reliable bounds can be placed on the mass of the Z gauge boson arising in such theories. In this work, we obtain 95% C.L. limits on the Z mass for several GUT-models using current and future proton-proton colliders with √ s = 13 TeV, 33 TeV, and 100 TeV, and put them into perspective with dark matter searches in light of the next generation of direct detection experiments.Dedicated to the memory of Pierre Binétruy PACS numbers: 2 Our analysis is focused on hadron colliders. Linear e + e − would be also an interesting option [9].
