We report the measurement of sin 2 W in ? N deep inelastic scattering from the NuTeV experiment. Using separate neutrino and anti-neutrino beams, NuTeV is able to determine sin 2 W with low systematic errors by measuring the Paschos-Wolfenstein variable R ? , a ratio of diierences of neutrino and anti-neutrino neutral-current and charged-current cross-sections. NuTeV measures sin 2 W (on?shell) =

A sequence of excited states has been established for the first time in proton-rich nucleus 48Fe (Z=26, N=22). The technique mirrored (i.e. analogue) one-nucleon knockout reactions was applied, which Tz= ±2 mirror pair, 48Fe/48Ti were populated via one-neutron/one-proton from secondary beams 49Fe/49V, respectively. analogue properties used to help establish new level scheme 48Fe. inclusive and ...

Measurements of the structure of the virtual photon in the transition region between quasi-real photons and those far from mass-shell have been made with the ZEUS detector at HERA, using an integrated luminosity of 38 pb. Dijet final states are identified, and differential cross sections are presented in terms of x γ , an estimator of the fraction of the photon energy which takes part in the QC...

Gamma decays were observed in 56Ca and 58Ca following quasi-free one-proton knockout reactions from 57,59Sc beams at ≈200 MeV/nucleon. For 56Ca, a γ ray transition was measured to be 1456(12) keV, while for an indication 1115(34) keV. Both transitions tentatively assigned as the 21+→0gs+ decays, compared results ab initio conventional shell-model approaches. A calculation wide model space with ...

The fusion evaporation-residue cross sections for 32 S+ 184 W has been mea-246, and 257 MeV using the ATLAS Fragment Mass Analyzer. The data are compared with Statistical Model calculations and it is found that a nuclear dissipation strength, which increases with the excitation energy is required to reproduce the excitation function. A comparison with previously published data show that the dis...

Screening of initial parton production due to the presence of on-shell partons in high-energy heavy-ion collisions is discussed. It is shown that the divergent cross sections in the calculation of parton production can be regulated self-consistently without an ad hoc cut-off, and that the resultant parton production and transverse energy production rate are finite. Consequences on the energy de...

In the framework of the impulse approximation we study the photoproduction of the hypertriton ΛH by using realistic He wave functions obtained as solutions of Faddeev equations with the Reid soft-core potential for different ΛH wave functions. We obtain relatively small cross sections of the order of 1 nb. We also find that the influence of Fermi motion is important, while the effect of differe...

The fusion cross-sections for 16 O + 208 Pb, measured to high precision, enable the extraction of the distribution of fusion barriers. This shows a structure markedly different from the single–barrier which might be expected for fusion of two doubly– closed shell nuclei. The results of exact coupled channel calculations performed to understand the observations are presented. These calculations ...
