A muon collider could produce the heavier Standard Model particles with a boost, for example in resonant processes such as μ−μ+→ h or μ−μ → Z. We propose machine configurations that produce the boost (asymmetric beam energies, tilted beams) and estimate how much the luminosity is reduced or perhaps enhanced. The feasibility of the proposed configurations, as well as an estimation of the beam-induced backgrounds and beam energy spread, needs to be evaluated in order to derive more solid conclusions on the physics potential of such boosted collider configurations. If achievable, the boost can provide new interesting observational opportunities. For example it can significantly enhance the sensitivity to long-lived new particles decaying in a far-away detector, such as dark higgses or sterile neutrinos produced in h or Z decays.

“…The idea is to represent the number of events as the integral of the product of several pre-computed quantities: the LLP angle-energy distribution, the geometric acceptance of the experiment, the LLP decay probability, and the acceptance for the decay products. This method has been successfully used for a number of experiments and LLPs [4][5][6] (see also [7,8]).…”

The increasing interest in Long-Lived Particles (LLPs) has led to numerous proposed experiments in order to search for them. However, the sensitivity estimates published by these experiments tend to rely on disparate assumptions. To ensure an accurate comparison of their potential to find LLPs, a unified estimation of their sensitivity is therefore required. In this contribution, we introduce SensCalc, a Mathematica-based code that uses a semi-analytic approach to calculate the event rate of GeV-scale LLPs, and we present several case studies.

“…Another such example is presented in the proposal of the additional subdetectors to be added to FCC-hh facilities to probe neural LLPs, with an example sensitivity to HNLs shown in Fig. 2 [19]. It allows to cover parameter space not accessible at the FCC-ee or SHiP experiments.…”
