Searches for magnetic monopoles and beyond with MoEDAL at the LHC

Abstract

Abstract.The MoEDAL experiment at the LHC is optimised to detect highly-ionising particles such as magnetic monopoles, dyons and (multiply) electrically-charged stable massive particles predicted in a number of theoretical scenarios. MoEDAL, deployed in the LHCb cavern, combines passive nuclear track detectors with magnetic monopole trapping volumes, while cavern backgrounds are being monitored with an array of MediPix detectors. The detector concept and its physics reach is presented with emphasis given to recent results on monopole searches providing the best limits on high magnetic charges in colliders. The potential to search for heavy, long-lived supersymmetric electrically-charged particles and multi-charged states is also discussed.

MoEDAL-MAPP - Detectors specialised for LLP searches

“…Its main motivation is the quest for magnetic monopoles [9,10], as well as any massive, detector-stable, slow-moving particle with single or multiple electric charge [11]. Various theoretical scenarios foresee the production of magnetic charge at the LHC [12]: (light) 't Hooft-Polyakov monopoles [13,14], electroweak monopoles [15][16][17][18][19], global monopoles [20][21][22][23][24][25][26], monopoles in Born-Infeld theory [27][28][29][30] and monopolium [10,[31][32][33][34][35][36][37], a monopole-pair bound state.…”

A Brief Discussion on the Performance of the MoEDAL and the LHCf Experiments

“…They are composed of pixel device arrays (256×256 square pixels with a pitch of 55 µm). Each pixel has the TimePix chip which consists of a preamplifier, a discriminator with threshold adjustment, synchronizing logic and a 14-bit counter [8].…”
