The e + e ! W + W cross section is measured in a data sample collected by ALEPH at a mean centre{of{mass energy of 172.09 GeV, corresponding to an integrated luminosity o f 10.65 pb 1 . Cross sections are given for the three topologies, fully leptonic, semi-leptonic and hadronic of a W-pair decay. Under the assumption that no other decay modes are present, the W-pair cross section is measured to be 11:7 1:2(stat:) 0:3(syst:) pb: The existence of the triple gauge boson vertex of the Standard Model is clearly preferred by the data. The decay branching ratio of the W boson into hadrons is measured to beB(W ! hadrons) = 67:7 3:1(stat:) 0:7(syst:) %, allowing a determination of the CKM matrix element jV cs j = 0 : 98 0:14(stat:) 0:03(syst:).

“…To identify a scintillation signal well above the background due to the intrinsic induced radioactivity after proton irradiation, we have triggered on cosmic muons traversing the crystal sideways, by means of two plastic scintillators. Such muons are minimum-ionising, and leave, according to [38], an energy deposit of 7.9 MeV/cm in the crystal. Due to the geometrical acceptance of the trigger scintillator setup, the mean path in the crystal is 2.3 ± 0.2 cm.…”

A CeF 3 crystal produced during early R&D studies for calorimetry at the CERN Large Hadron Collider was exposed to a 24 GeV/c proton fluence Φ p = (2.78±0.20)×10 13 cm −2 and, after one year of measurements tracking its recovery, to a fluence Φ p = (2.12 ± 0.15) × 10 14 cm −2 . Results on protoninduced damage to the crystal and its spontaneous recovery after both irradiations are presented here, along with some new, complementary data on proton-damage in Lead Tungstate. A comparison with FLUKA Monte Carlo simulation results is performed and a qualitative understanding of high-energy damage mechanism is attempted.

“…The mass values obtained for cc and bb systems, with the parameters in Table 1, are presented in Figure 1 together with the theoretical values obtained by Fulcher [29] and compared with the experimental values [23] (the results for each potential are presented in the figure as columns). The experimental masses of the states 1S, 1P , 2S for the charmonium systems and all the ones presented for the Upsilom systems are spin averaged and were used in our fit of the parameters.…”

“…As we will work with a spin independent model, the magnitudes we will deal with will be spin averaged. For fitting our parameters spin averages of experimental values were calculated, but for certain resonances the experimental values were not at hand [23] and theoretical results obtained by Fulcher [24] were used. It should be mentioned that in a work by Hirata et al [25] the harmonic oscillator was employed as an unperturbed confinement potential, in the asymptotically free coloredquark-gluon model in which the one-gluon-exchange force was treated perturbatively.…”

Hadron spectra and other properties of quark systems are studied in the framework of a non-relativistic spinindependent phenomenological model. The chosen confining potential is harmonic, which allowed us to obtain analytical solutions for both meson and baryon (of equal constituent quarks) spectra. The introduced parameters are fixed from the low-lying levels of heavy quark mesons. The requirement of flavor independence is imposed, and it restricts the possible choices of inter-quark potentials. The hyper-spherical coordinates are considered for the solution of the three-body problem.Espectros de Hadrons e outras propriedades de sistemas de quarks são estudados do ponto de vista de um modelo fenomenológico não-relativístico independente de spin. O potencial confinante escolhidoé harmônico, o qual nos permite obter soluções analíticas tanto para os espectros dos mésons quanto para os dos bárions (de iguais quarks constituintes). Os parâmetros introduzidos são fixos a partir dos primeiros estados excitados dos mésons pesados. A condição de independência de saboré imposta, o que restringe as possíveis escolhas de potenciais inter-quarks. As coordenadas hiper-esféricas são consideradas para a solução do problema de três corpos.
