Hadrophilic dark sectors at the Forward Physics Facility

FLArE up dark sectors with EM form factors at the LHC Forward Physics Facility

“…In our discus-sion, we focus on electron-recoil signals induced by new physics species. These can be more efficiently disentangled from neutrino-induced backgrounds than signatures based on scatterings off nuclei [108,109], especially in searches targeting low energy depositions in the detector. In the following, we discuss several strategies to maximize the sensitivity reach and we comment on expected backgrounds.…”

A Snowmass Whitepaper: Dark Matter Production at Intensity-Frontier Experiments

“…In Figs 6b and 6c we present the projected exclusion bounds for the search for hadrophilic DM scattering signatures in the CCM200 [26,50], FLArE [51], PIP2 BD [52], and SND@LHC [53] experiments, as well as the relevant future bounds from missing energy/momentum searches at NA64 [22,54] and LDMX-II [55]. These have been obtained for the U (1) B−3 Lτ (left panel) and U (1) B (right) gauge boson V coupled to the DM particles with α D = 0.5.…”

“…In the plots, past bounds are shown with a gray-shaded region following Ref. [51]. These include anomaly-driven bounds from rare kaon, B meson, and Z decays shown in light gray for the U (1) B case [49,56].…”

“…We present the past bounds on the model with gray-shaded regions following Ref. [51]. Invisibly Decaying Scalar Mediator, Dirac DM, g = 1, m = 3 m FIG.…”

Sensitivities on dark photon from the forward physics experiments

“…Proton-proton collisions at the Large Hadron Collider (LHC) produce many particles along the beam axis. Forward Physics Facilities (FPF) [13][14][15][16][17][18][19][20][21][22], situated several hundred meters away from the ATLAS interaction point and protected by concrete and rock, will host a wide variety of experiments probing the SM processes and also searching for new physics beyond the standard model (BSM) [13,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. Each experiment in the FPF is uniquely optimized for its own physics goals.…”
