μ+e− ←→ μ−e+ Transitions via Neutral Scalar Bosons

چکیده
With μ → eγ decay forbidden by multiplicative lepton number conservation, we study muonium–antimuonium transitions induced by neutral scalar bosons. Pseudoscalars do not induce conversion for triplet muonium, while for singlet muonium, pseudoscalar and scalar contributions add constructively. This is in contrast to the usual case of doubly charged scalar exchange, where the conversion rate is the same for both singlet and triplet muonium. Complementary to muonium conversion studies, high energy μe → μe and ee → μμ collisions could reveal spectacular resonance peaks for the cases of neutral and doubly charged scalars, respectively.

Decay-mode independent searches for new scalar bosons with OPAL
Searches for new neutral CP even scalar bosons S with the OPAL [1] detector at LEP are described. The new bosons are assumed to be produced in association with a Z boson via the Bjorken process e+e− → SZ. The analyses are topological searches and are based on studies of the recoil mass spectrum in Z → e+e− and μ+μ− events and on a subsequent search for SZ events with S → e+e− or photons and Z →...
متن کاملHigh Energy FCNC search through eμ Colliders
We study the potential impacts of a new type of particle collider – an eμ collider – on the search for new physics beyond the Standard Model. As our first attempt for exploring its physics potential, we demonstrate that the the eμ collision experiment can be highly efficient in searching for lepton-number-violating Flavor Changing Neutral Current phenomena.

متن کاملRadiative Lepton Masses with Heavy Lepton Seed
We construct a Z8 model for leptons where all Yukawa couplings are of order unity, but known lepton masses are generated radiatively, order by order. The seed is provided by fourth generation leptons E and N , which receive (Dirac) mass in usual way. Two additional Higgs doublets with nontrivial Z8 charge are introduced to give nearest neighbor Yukawa couplings. Hence, nonstandard Higgs bosons ...
متن کاملFlavor Changing Neutral Currents at μ + μ − Colliders
We illustrate the possibility of observing signals from Flavor Changing Neutral Currents, originating from the scalar sector of a Two Higgs Doublet Model. In particular, we focus on the tree level process µ + µ − → ¯ tc + ¯ ct, via scalar exchange in the s-channel, as a distinctive process for µ + µ − colliders.
متن کاملBileptons - Present Constraints and Future Prospects at Colliders
Bosons which couple to two leptons and carry lepton number L = 2, generically called bileptons, appear in many extensions of the SM. We review the present constraints on bilepton parameters coming from low and high energy data. In particular, we point out that the amplitude of μ − e conversion in nuclei is enhanced by large logarithms if compared with the μ → eγ one. Bilepton couplings will be ...
