“…In a previous work [41], the potential to search for CLFV signals induced by the Z ′ model has been studied at the future lepton colliders. In this paper, we focus on the search for CLFV at CEPC and the Muon Collider with RPV-MSSM assumed.…”

Interest in searches for Charged Lepton Flavor Violation (CLFV) has continued in the past few decades since the observation of CLFV would indicate a new physics Beyond the Standard Model (BSM). As several future lepton colliders with high luminosity have been proposed, the search for CLFV will reach an unprecedented level of precision. Many BSM models allow CLFV processes at the tree level, such as the R-parity-violating (RPV) Minimal Supersymmetric Standard Model (MSSM), which is a good choice for benchmarking. In this paper, we perform a detailed fast Monte Carlo simulation study on RPV-induced CLFV processes at future lepton colliders, including a 240 GeV circular electron positron collider (CEPC) and a 6 or 14 TeV Muon Collider. As a result, we found that the upper limits on the τ-related RPV couplings will be significantly improved, while several new limits on RPV couplings can be set, which are inaccessible by low-energy experiments.

We derive the discovery potential of a leptophilic $$Z^\prime $$ Z ′ , and a $$Z^\prime $$ Z ′ rising from a $$SU(3)_C \times SU(3)_L \times U(1)_N$$ S U ( 3 ) C × S U ( 3 ) L × U ( 1 ) N symmetry at the Compact Linear Collider (CLIC), which is planned to host $$e^+e^-$$ e + e - collisions with 3 TeV center-of-mass energy. We perform an optimized selection cut strategy on the transverse momentum, pseudorapidity, and invariant mass of the dileptons in order to enhance the collider sensitivity. We find that CLIC can potentially reach a $$5\sigma $$ 5 σ signal of a $$1-5$$ 1 - 5 TeV leptophilic $$Z^\prime $$ Z ′ with less than 1 fb$$^{-1}$$ - 1 of integrated luminosity in the most favorable cases. As for the $$Z^\prime $$ Z ′ belonging to a 3-3-1 symmetry, CLIC will offer a complementary probe with the potential to impose $$M_{Z^\prime } > 3$$ M Z ′ > 3 TeV with $${\mathcal {L}}=2$$ L = 2 fb$$^{-1}$$ - 1 .
