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 ...

On the presence of a fifth force at the Galactic Center ...

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 ...

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, ...

Digital design of integrated circuits in nanometer technology requires to address several design challenges. Among those, system complexity has to be handled with modern techniques and tools, power ...

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 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% ...

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 ...

Twelve ground state transitions up to about 5 MeV have been observed by the resonant scattering of bremsstrahlung from natural barium. Six of the first seven lines are from 2+ states in Ba138 as ...

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 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 ...
