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, ...

In this paper it is shown that the classical maximum likelihood principle can be considered to be a method of asymptotic realization of an optimum estimate with respect to a very general information ...

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% ...

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 ...

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 study of neutrinos and their interaction with matter has made many important contributions to our present knowledge of physics. This advanced text introduces neutrino physics and presents a ...

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 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 ...
