By splitting the Coulomb interaction into long-range and short-range components, we
decompose the energy of a quantum electronic system into long-range and short-range …

Silicon sensors have been used in High Energy Physics for about 25 years. They have been
continuously improved to meet new requirements and challenges. Based on a simple …

Results are presented on hyperon and antihyperon production in Pb–Pb, pPb and pBe
collisions at 158 GeV/c per nucleon. Λ, Ξ and Ω yields have been measured at central …

A measurement of strange baryon and antibaryon production in Pb–Pb collisions has been
carried out by the NA57 experiment at the CERN SPS, with 40 and 158 AGeV/c beam …

We calculate the linear torque exerted by a planet on a circular orbit on a disc containing a
toroidal magnetic field. All fluid perturbations are singular at the so-called magnetic …

Results are presented on the production of K 0 S, hyperons and antihyperons in Pb–Pb and
p–Be interactions at 40 GeV/c per nucleon. The enhancement pattern follows the same …

The NA57 experiment has collected high statistics, high purity samples of K 0 S and Λ, Ξ and
Ω hyperons produced in Pb–Pb collisions at 158 A GeV/c. In this paper we present a study of …

We measure the dependence of B¯ 0→ D*+ e-ν¯ e on the decay angles and momentum
transfer. The data sample consists of∼ 86× 10 6 BB¯-pairs accumulated on the Υ (4 S) …

The procedure employed by the WA97 and NA57 experiments to determine the number of
wounded nucleons in different Pb+ Pb centrality classes is discussed. We will also compare …

The ALICE1LHCB pixel readout chip emerged from previous experience at CERN. The RD-
19 collaboration provided the basis for the installation of a pixel system in the WA97 and …
