CP-violating signals in weak Ξ → πΛ decay require the knowledge of πΛ Sand P-wave scattering phases at m Ξ center-of-mass energy. We have calculated these phases in baryon chiral perturbation theory with the ground-state Σ in s and u channels and 3 2 + Σ(1385) in the u channel. We do not treat the baryons as heavy. We find δ S = 1.2 • and δ P = −1.7 • with the central value of the strong coupli...

We study the achievable accuracy for measuring the ZZh coupling (g ZZh) of a light (mh <∼ 140GeV) SM-like Higgs boson at ee linear colliders in a model-independent way. At a 500 GeV linear collider, including the (dominant) ZZ-fusion process dramatically increases the precision that can be achieved using only the Zh associated production process; after combining, errors of <∼ 5% − 8% are achiev...

The anisotropy of the positrons emitted in the reaction νe + p → n + e + has to be taken into account for extracting an antineutrino signal in Superkamiokande. For the Sun, this effect allows a sensitivity to νe → νe transition probability at the 3% level already with the statistics collected in the first hundred days. For a supernova in the Galaxy, the effect is crucial for extracting the corr...

Here is presented a complete work on the (1+1) dimensional SU(N) YangMills theory with static sources. By studying the structure of the SU(N) group and of the Gauss’ law we construct in the electric representation the appropriate wave functionals, which are simultaneously eigenstates of the Gauss’ operator and of the Hamiltonian. Special consideration has been given on the Fourier transformatio...
