The REDTOP experiment: a $η/η^{\prime}$ factory to explore dark matter and physics beyond the Standard Model

The REDTOP experiment is a proposed super-$η$/$η'$ factory aimed at exploring physics beyond the Standard Model in the MeV-GeV range and rare $η$/$η'$ meson decays. With projected production rates exceeding $10^{13}$ $η$/year and $10^{12}$ $η'$/year, REDTOP will enable studies of symmetry violations and all four portals to the Dark Sector. Preliminary studies show sensitivity, which could open a broad possibility for exploring new physics and contribute to a deeper understanding of fundamental interactions within the Standard Model. Such high statistics experiments and the required sensitivity can only be achieved with a high intensity proton or pion beam, available at several accelerator facilities worldwide. This article discusses the physics potential of the REDTOP experiment, the detector design, and the future beam requirements.

Experiments and Facilities for Accelerator-Based Dark Sector Searches

This paper provides an overview of experiments and facilities for accelerator-based dark matter searches as part of the US Community Study on the Future of Particle Physics (Snowmass 2021). Companion white papers to this paper present the physics drivers: thermal dark matter, visible dark portals, and new flavors and rich dark sectors.

Physics Opportunities for the Fermilab Booster Replacement

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.

The REDTOP experiment

The $η$ and $η$' mesons are almost unique in the particle universe since they are Goldstone and the dynamics of their decays are strongly constrained. Because the $η$ has no charge, decays that violate conservation laws can occur without interfering with a corresponding current. The integrated η-meson samples collected in earlier experiments amount to $\sim10^{9}$ events, dominated by the WASA-at-Cosy experiment. A new experiment, REDTOP (Rare Eta Decays with a TPC for Optical Photons), is being proposed, either at the proton Delivery Ring of Fermilab or at the Proton Synchrotron of CERN, with the intent of collecting in excess of $10^{12} η/yr$ ($10^{10}$ $η'/year$) for studying rare decays. Such statistics are sufficient for investigating several symmetry violations, and for searching particles beyond the Standard Model. Recent studies have indicated that REDTOP has very good sensitivity to processes that couple the Standard Model to new physics through three of the so-called portals: the vector, the scalar and the axion portal. An upgraded version of the detector will be proposed, at a later stage, for a run at the PIP-II accelerator complex, where the $η$ mesons will be produced in tagged mode. The physics program, the accelerator systems and the detector for REDTOP are discussed.

Status of Dual-readout R&D for a linear collider in T1015 Collaboration

The hadronic energy resolution required for an hadronic operating at lepton collider is at the limits or even exceeds that obtained with traditional techniques. Furthermore, it is a well established fact that the presence of an electromagnetic section in front of an hadron calorimeter, as occurs in the layouts of the majority of detectors operating at a collider, would deteriorate the hadronic energy resolution of the device. The novel $ADRIANO$ technology (\textit{A Dual-readout Integrally Active Non-segmented Option}), currently under development at Fermilab, overcomes the above limitations by complementing an integrally active calorimeter with the dual-readout technique. Detailed Monte Carlo studies indicate that the energy resolution is in the $25\%/\sqrt{E}$ - $38\%/\sqrt{E}$ interval with a linear response of the detector up to an energy of 200 GeV. A baseline configuration is chosen with an estimated energy resolution of $σ(E)/E\approx30\%/\sqrt{E}$. Several prototypes have been built by \textit{T1015} Collaboration at Fermilab, to explore the effect of modifications of the layout from the baseline configuration. Preliminary results from several test beams at the \textit{Fermilab Test Beam Facility} (FTBF) of $\sim1λ_{I}$ prototypes are presented. Future prospects with ultra-heavy glass are, also, summarized.

The Case for a Muon Collider Higgs Factory

We propose the construction of a compact Muon Collider Higgs Factory. Such a machine can produce up to \sim 14,000 at 8\times 10^{31} cm^-2 sec^-1 clean Higgs events per year, enabling the most precise possible measurement of the mass, width and Higgs-Yukawa coupling constants.
