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 ...

Conformal Einstein equation and symplectic flux with a positive cosmological constant ...

A comprehensive description of the muon storage ring and its operation is given, and the final results of the experiment are presented and discussed. The anomalous magnetic moments of positive and ...

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 ...

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, ...

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 ...

Polarization effects are considered in colliding γe and γγ beams, which are proposed to be obtained on the basis of linear e + e − colliders (by backward Compton scattering of laser light on electron ...

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 ...

We present a calculation of the three-loop metric β-function for the bosonic non-linear sigma model. We also construct the action whose equations of motion coincide with the vanishing of the ...

We develop a Generalized-Vector-Meson Dominance Model (GVDM) for the invariantN-Δ transition form factors which incorporates the correct largeq2 power behaviour of QCD and describes the available ...

We study the limit when the σ mass is very large compared to other scales in the renormalized light-particle-irreducible Green's functions of the linear σ model with SO(N+1) symmetry. This is a strong ...
