The current theoretical understanding of anomalous gauge boson couplings is reviewed, and the direct measurement of these couplings in present and future hadron collider experiments is briefly discussed. Talk given at the International Europhysics Conference on High Energy Physics, Brussels, Belgium, July 27 – August 2, 1995 Self-Couplings of Electroweak Bosons: Theoretical Aspects and Tests at...

Electron scattering from a hadron target has a singularly attractive feature relative to the various processes of hadrons scattering from hadron targets: the electromagnetic field generated during the electrons’s scattering is understood if indeed anything is in particle physics. Dirac’ tells us the transition current of the ,scattered electron and Maxwell tells us the rest. Therefore, in this ...

To understand the whole set of positive and null data on the Θ(1530)-production, we suggest the hypothesis that multiquark hadrons are mainly generated from many-quark states, which emerge either as short-term hadron fluctuations, or as hadron remnants in hard processes. This approach allows us to describe both non-observation of the Θ in current null experiments and peculiar features of its pr...

Simulation of gamma and hadron showers in the energy range 100GeV- 25TeV has been carried out. For a big ideal Cherenkov light array, characteristics of lateral distribution of Cherenkov photon density have been studied. Results from this ideal detector are compared with those simulated for a real TUNKA- like array to investigate experimental potential of using existence of a hump in lateral di...

This report summarizes the quality requirements to the barium fluoride (BaF 2 ) crystals for constructing a high precision electromagnetic calorimeter at future hadron colliders . The basic property of BaF2 crystals and the design and performance of a BaF2 calorimeter are presented . The emphasis of the discussion is in the radiation resistance of the current production BaF2 crystals. An approa...

We present a formalism that improves the applicability of perturbative QCD in the current region of semi-inclusive deep inelastic scattering. The formalism is based on all-order resummation of large logarithms arising in the perturbative treatment of hadron multiplicities and energy flows in this region. It is shown that the current region of semi-inclusive DIS is similar to the region of small...

Abstract Light charged hadron production data in the current fragmentation region at HERA are calculated using next-to-leading order perturbative calculations and fragmentation functions obtained from similar data from e+e− reactions. General good agreement is found at large photon virtuality Q2 and intermediate momentum fraction xp, consistent with fragmentation function universality. The desc...
