The abundance of relativistic axions in a flaton model of Peccei-Quinn symmetry
Eung Jin Chun, Denis Comelli, David H. Lyth
Flaton models of Peccei-Quinn symmetry have good particle physics motivation, and are likely to cause thermal inflation leading to a well-defined cosmology. They can solve the …
The Early Mirror Universe: Inflation, Baryogenesis, Nucleosynthesis and Dark Matter
Zurab Berezhiani, Denis Comelli, Francesco L. Villante
There can exist a parallel `mirror' world which has the same particle physics as the observable world and couples the latter only gravitationally. The nucleosynthesis bounds demand…
Electroweak double logarithms in inclusive observables for a generic initial state
M. Ciafaloni, P. Ciafaloni, D. Comelli
High energy observables are characterized by large electroweak radiative corrections of infrared origin; double logarithms are present even for inclusive cross sections, thus viola…
Electroweak Bloch-Nordsieck violation at the TeV scale: "strong" weak interactions ?
M. Ciafaloni, P. Ciafaloni, D. Comelli
Hard processes at the TeV scale exhibit enhanced (double log) EW corrections even for inclusive observables, leading to violation of the Bloch-Nordsieck theorem. This effect, previ…
Bloch-Nordsieck violating electroweak corrections to inclusive TeV scale hard processes
M. Ciafaloni, P. Ciafaloni, D. Comelli
We point out that, since the colliders initial states (e+ e-,p p, p pbar, ... ) carry a definite nonabelian flavor, electroweak radiative corrections to inclusive hard cross sectio…
