Signatures of Spontaneous Breaking of R-Parity in Gluino Cascade Decays at LHC
A. Bartl, W. Porod, F. de Campos +4
We study the pattern of gluino cascade decays in a class of supersymmetric models where R-parity is spontaneously broken. We give a detailed discussion of the R-parity violating de…
Tau Lepton Physics: Theory Overview
A. Pich
The pure leptonic or semileptonic character of tau decays makes them a good laboratory to test the structure of the weak currents and the universality of their couplings to the gau…
Single-Photon Z Decays and Small Neutrino Masses
J. C. Romao, S. D. Rindani, J. W. F. Valle
We discuss some rare Z decay signatures associated with extensions of the Standard Model with spontaneous lepton number violation at the electroweak scale. We show that single-phot…
Hard Corrections as a Probe of the Symmetry Breaking Sector
D. Comelli, J. Bernabeu, A. Pich +1
Non-decoupling effects related to a large affecting non-oblique radiative corrections in vertices () and boxes (- mixing and ) are very sensitive…
Baryogenesis from mixed particle decays
L. Covi, E. Roulet
We consider the violating asymmetries produced in the decay of heavy particles, studying the effects of heavy particle mixing for arbitrary mass splittings. A considerable enh…
Constraints on doubly charged Higgs interactions at linear collider
G. Barenboim, K. Huitu, J. Maalampi +1
Production of a single doubly charged Higgs boson in polarized and collision modes of the linear collider have been investigated. The mass range of $De…
