Particle creation from non-topological solitons

Non topological solitons, Q balls can arise in many particle theories with U(1) global symmetries. As was shown by Cohen et al. [2], if the corresponding scalar field couples to massless fermions, large Q-balls are unstable and evaporate, producing a fermi ...

Flavour effects on leptogenesis predictions

Steve Blanchet

Flavor effects in leptogenesis reduce the region of the see-saw parameter space where the final predictions do not depend on the initial conditions, the strong wash-out regime. In this case we show that the lowest bounds holding on the lightest right-hande ...

Extended law of corresponding states in short-range square wells: A potential energy landscape study

Giuseppe Foffi, Francesco Sciortino

We study the statistical properties of the potential energy landscape of a system of particles interacting via a very short-range square-well potential (of depth - u0) as a function of the range of attraction Δ to provide thermodynamic insights of the Noro ...

Gravitational quantum corrections in warped supersymmetric brane worlds

Riccardo Rattazzi, Claudio Scrucca

We study gravitational quantum corrections in supersymmetric theories with warped extra dimensions. We develop for this a superfield formalism for linearized gauged supergravity. We show that the 1-loop effective Kahler potential is a simple functional of ...

Diffusivity and configurational entropy maxima in short range attractive colloids

Giuseppe Foffi, Francesco Sciortino

We study tagged particle diffusion at large packing fractions, for a model of particles interacting with a generalized Lennard-Jones 2n-n potential, with large n. The resulting short range potential mimics interactions in colloidal systems. In agreement wi ...

A Novel Low Noise Hydrogenated Amorphous Silicon Pixel Detector

Arvind Shah, Matthieu Despeisse

Firsts results on particle detection using a novel silicon pixel detector are presented. The sensor consists of an array of 48 square pixels with 380 μm pitch based on a n-i-p hydrogenated amorphous silicon (a-Si:H) film deposited on top of a VLSI chip. Th ...

Evidence for direct CP violation in B0 → K+ π- decays

Aurelio Bay, Stewart Cole, Tagir Aushev

The evidence for direct charged particles (CP) violation in the decay B0→K+ π- was investigated with 253 fb-1 of data collected with the Belle detector at the KEKB e + e- collider. 275 x 106 BB̄ pairs were used to observe a B→K±π∓ signal with 2140 ±53 even ...

Single- and multi-photon events with missing energy in e+e - collisions at LEP

Aurelio Bay

Single- and multi-photon events with missing energy are selected in 619 pb-1 of data collected by the L3 detector at LEP at centre-of-mass energies between 189 and 209 GeV. The cross sections of the process e +e-→νν̄γ(γ) are found to be in agreement with t ...

Evidence for an unusual dynamical-arrest scenario in short-ranged colloidal systems

Giuseppe Foffi, Francesco Sciortino

Extensive molecular dynamics simulation studies of particles interacting via a short-ranged attractive square-well potential arc reported. The calculated loci of constant diffusion coefficient D in the temperature-packing fraction plane show a reentrant be ...

Phenomenology of deflected anomaly-mediation

Riccardo Rattazzi

We explore the phenomenology of a class of models with anomaly-mediated supersymmetry breaking. These models retain the successful flavor properties of the minimal scenario while avoiding the tachyons. The mass spectrum is predicted in terms of a few param ...
