“…This would result in the reach of large regions of unexplored parameter space of many dark sector models: (1) minimal models containing a "mediator" particle decaying resonantly to two SM particles (e.g. a dark photon decaying into an electron-positron pair), see [63][64][65][66][67] for the study of minimal dark sector models at DarkQuest; (2) non minimal models containing, for example, an excited DM state that decays to the DM candidate together with visible particles, as it happens e.g. in strongly interacting massive particle (SIMP) dark matter [15] or in models of inelastic DM [64].…”

This white paper presents opportunities afforded by the Fermilab Booster Replacement and its various options. Its goal is to inform the design process of the Booster Replacement about the accelerator needs of the various options, allowing the design to be versatile and enable, or leave the door open to, as many options as possible. The physics themes covered by the paper include searches for dark sectors and new opportunities with muons.

Expanding the mass range and techniques by which we search for dark matter is an important part of the worldwide particle physics program. Accelerator-based searches for dark matter and dark sector particles are a uniquely compelling part of this program as a way to both create and detect dark matter in the laboratory and explore the dark sector by searching for mediators and excited dark matter particles. This paper focuses on developing the DarkQuest experimental concept and gives an outlook on related enhancements collectively referred to as LongQuest. DarkQuest is a proton fixed-target experiment with leading sensitivity to an array of visible dark sector signatures in the MeV-GeV mass range. Because it builds off of existing accelerator and detector infrastructure, it offers a powerful but modest-cost experimental initiative that can be realized on a short timescale.

“…While this work was undergoing finalization, an independent study of the DarkQuest sensitivity to ALPs has appeared[53], using 7-8 m as fiducial volume (following[52], whereas our fiducial volume definition follows[51]). Apart from this major difference in the acceptance simulation, there are slight differences regarding the overall required energy and the photon separation.11 Note that this requirement goes slightly beyond that made in Ref [51],.…”

Proton beam dump experiments are among the most promising strategies to search for light and feebly interacting states such as axion-like particles (ALPs). The interpretation of these experiments is however complicated by the wide range of ALP models and the multitude of different production and decay channels that can induce observable signals. Here we propose a new approach to this problem by separating the calculation of constraints and projected sensitivities into model-independent and model-dependent parts. The former rely on extensive Monte Carlo simulations of ALP production and decays, as well as estimates of the detection efficiencies based on simplified detector geometries. Once these simulations have been performed and tabulated, the latter parts only require simple analytical rescalings that can be performed using the public code ALPINIST released together with this work. We illustrate this approach by considering several ALP models with couplings to Standard Model gauge bosons. For the case of ALPs coupled to gluons we show that the sensitivity of proton beam dump experiments can be extended significantly by considering hadronic ALP decays into three-body final states.
