Electroweak Sudakov form factors and nonfactorizable soft QED effects at NLC energies
P. Ciafaloni, D. Comelli
We study the leading log infrared behavior of electroweak corrections at TeV scale energies, that will be reached by next generation of linear colliders (NLC). We show that, contra…
The role of the top mass in b-production at future lepton colliders
M. Beccaria, P. Ciafaloni, D. Comelli +2
We compute the one loop contribution coming from vertex and box diagrams, where virtual top quarks are exchanged, to the asymptotic energy behaviour of pair production at…
Logarithmic expansion of electroweak corrections to four-fermion processes in the TeV region
M. Beccaria, P. Ciafaloni, D. Comelli +2
Starting from a theoretical representation of the electroweak component of four-fermion neutral current processes that uses as theoretical input the experimental measurements at th…
Flatons and Peccei-Quinn Symmetry
E. J. Chun, D. Comelli, David H. Lyth
We study in detail a supersymmetric Peccei-Quinn model, which has a DFSZ and a KSVZ version. The fields breaking the Peccei-Quinn (PQ) symmetry correspond to flat directions (flato…
The Sphaleron in a Magnetic Field and Electroweak Baryogenesis
D. Comelli, D. Grasso, M. Pietroni +1
The presence of a primordial magnetic field in the early universe affects the dynamic of the electroweak phase transition enhancing its strength. This effect may enlarge the window…
