Two‐to‐Two Processes at an Electron‐Muon Collider
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Based on a recent proposal to build an electron‐muon collider, we study two‐to‐two production processes e−μ+⟶ff¯, γγ that originate from dimension 6 and 8 operators. We compare the sensitivity to those effective couplings obtained at the collider with that of low energy measurements of μ⟶eγ, μ⟶ee¯e, and μ⟶e conversion that have recently been reported ...

On the Impact of the LHC Run 2 Data on General Composite Higgs Scenarios
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We study the impact of Run 2 LHC data on general composite Higgs scenarios, where nonlinear effects, mixing with additional scalars, and new fermionic degrees of freedom could simultaneously contribute to the modification of Higgs properties. We obtain new experimental limits on the scale of compositeness, the mixing with singlets and doublets with the

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Fortschritte der Physik, Volume 72, Issue 1, January 2024.Abstract Within the assumption of Left‐Handed (LH) New Physics (NP), the relations between B(B→K(*)τ+τ−)$\mathcal {B}(B\rightarrow K^{(\ast )} \tau ^+\tau ^-)$ and B(B→K(*)νν¯)$\mathcal {B}(B\rightarrow K^{(\ast )} \nu \bar{\nu })$ for several Beyond the Standard Model (BSM) scenarios are reviewed, commonly considered to explain the Lepton flavor ...

Top Quark Flavor Changing Couplings at a Muon Collider
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.
