Various recent results of new particle searches at the Fermilab Tevatron are presented. No evidence is found for supersymmetric particles (chargino, gluino), leptoquark bosons and heavy gauge bosons in pp̄ collisions at √ s = 1.8 TeV. Excluded mass regions for each particle are determined.

I discuss the importance of the O(g4m2t/M 2 W ) corrections to the effective electroweak angle and MW in the indirect determination of the Higgs mass. I emphasize the rôle of a very preciseMW measurement on the MH estimate. ∗ Talk presented at the Zeuthen Workshop on Elementary Particle Theory ”Loops and Legs in Gauge Theories” Rheinsberg, Germany, April 19-24, 1998

Based on the model of a ”soft” cellular space and deterministic quantum mechanics developed previously, the scattering of a free moving particle by structural units of the space – superparticles – is studied herein. The process of energy and inert mass transmission from the moving particle to superparticles and hence the creation of elementary excitations of the space – inertons – are analyzed ...

Off-line recognition of handwritten words is a difficult task due to the high variability and uncertainty of human writing. The majority of the recent systems are constrained by the size of the lexicon to deal with and the number of writers. In this paper, we propose an approach for multi-writers Arabic handwritten words recognition. The developed method uses multiple sources of information at ...

M AY 2 0 0 5 Ever since physicists invented particle accelerators, nearly 80 years ago, they have used them for such exotic tasks as splitting atoms, transmuting elements, producing antimatter and creating particles not previously observed in nature. With luck, though, they could soon undertake a challenge that will make those achievements seem almost pedestrian. Accelerators may produce the mo...

We derive compact analytical formulae of the Bonneau-Martin type for the reaction e + e − → ¯ f f γ with cuts on minimal energy and acollinearity of the fermions, where the photons may be emitted both from the initial or final states. Soft photon exponentiation is also taken into account. One of the cleanest scattering processes at elementary particle accelerators is fermion-pair production in ...

One of the major goals of the Large Hadron Collider is to probe the electroweak symmetry breaking mechanism and the generation of the masses of the elementary particles. We review the physics of the Higgs sector in the Standard Model and some of its extensions such as supersymmetric theories and models of extra dimensions. The prospects for discovering the Higgs particles at the LHC and the stu...

The BABAR Collaboration has an intensive program studying the cross sections of hadron production in low-energy e+e− annihilation, accessible via initial-state radiation. Our measurements allow a significant improvement in the precision of the predicted value of the muon anomalous magnetic moment. These improvements are necessary for shedding light on the current > 3 sigma difference between th...
