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 ...

The requirement that P and T be approximately conserved in the color gauge theory of strong interactions without arbitrary adjustment of parameters is analyzed. Several possibilities are identified, ...

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 ...

THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables. These additional ...

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% ...

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 ...

The isospin-forbidden reaction d+d→π0+4He provides a very good test of the validity of charge symmetry. The forward differential cross section dσ/dΩ is estimated to be ≊0.12 pb/sr at a deuteron ...

Signatures of NED on Quasi periodic Oscillations of a Magnetically Charged Black Hole ...

The WIMP limit set by the Xenon10 experiment in 2007 signals a new era in direct detection of dark matter, with several large-scale liquid target detectors now under construction. A major challenge in ...

Formulae for the line-of-sight and transverse comoving distances, proper motion distance, angular diameter distance, luminosity distance, k-correction, distance modulus, comoving volume, lookback time ...
