We are proud to announce that the INFN section of Pisa together with the Universities of Pisa and Siena will host the Higgs Pairs Workshop in the Hotel Hermitage, La Biodola, situated on the wonderful ...

We show how the BRST symmetry of Witten's topological field theory arises as a Killing spinor in N =2 conformal supergravity. We extend the model to include the twisted N =2 scalar multiplet, thus ...

We consider the three-dimensional Dirac equation in spherical coordinates with coupling to static electromagnetic potential. The space components of the potential have angular (non-central) dependence ...

Differential cross sections were measured for pion elastic and inelastic scattering from Ca40,42,44,48 and Fe54 at Tπ=116.0,180.0, and 292.5 MeV. Elastic scattering was analyzed using a Kisslinger ...

Four-point correlation functions are calculated for the basic operators in 2D conformal invariant theories with the central charge of the corresponding Virasoro algebra C ≤1. Based on these results, ...

If high energy heavy ion collisions lead to the formation of a hot quark-gluon plasma, then colour screening prevents cc binding in the deconfined interior of the interaction region. To study this ...

In this paper we present a 32 channel ASIC prototype for the readout of the silicon drift detectors (SDDs) of the ALICE experiment. The ASIC integrates on the same substrate 32 transimpedance ...

Using the data on deep inelastic muon scattering on iron and deuterium the ratio of the nucleon structure functions F 2 N ( Fe )/ F 2 N ( D ) is presented. The observed x -dependence of this ratio is ...

We compute the four-loop ( O ( α ′ 4 )) metric β-function for the two-dimensional bosonic non-linear σ-model. We employ an indirect method which avoids a large part of the explicit calculation and as ...

We study N=∞ lattice gauge theory at finite temperature by Monte Carlo methods using an asymmetric coupling version of the twisted Equchi-Kawai model. The data favor a first-order deconfining ...

The search for the decay μ + → e + e + e − with the SINDRUM spectrometer has been continued. The result is a new upper limit for the branching ratio B μ→3 e = Γ(μ→3 e ) Γ(μ→ e 2ν) < 1.0 × 10 −12 (90% ...
