چکیده
If supersymmetry is spontaneously broken at a low energy scale then the resulting gravitino will be very light. The interaction strength of the longitudinal components of such a light gravitino to e − ẽ pair then becomes comparable to that of electroweak interactions. If such a light gravitino is present it would significantly modify the crosssection for eLe − R → ẽLẽR from its MSSM value. Precision measurement of this cross-section could therefore be used to probe the low energy supersymmetry breaking scale Λs.

Caianiello’s quantum geometrical model with maximal acceleration places the upper limit μ ≤ 719.5 GeV on the mass of the Higgs boson. The model also provides an equation linking the mass of the W boson to the Higgs mass μ and independent symmetry breaking and mass generating mechanisms. These may further restrict the value of μ.

As the most recently discovered and heaviest quark, the top presents us with theoretical challenges. How are we to understand its properties within the larger effort to explain the origins of electroweak and flavor symmetry breaking ? This talk discusses some of the surprises the top quark may have in store for us and indicates how experiment may help us pinpoint the truth about top. Presented ...

In the case with a large splitting between the squark and slepton masses, the supersymmetric identities which enforce the equality of the gauge and gaugino couplings are violated in the effective theory below the squark mass threshold. We compute the full one-loop (s)quark corrected slepton production cross-sections. We find that the one-loop corrected slepton production cross-sections can depe...

We discuss the stability of multiquark systems containing heavy flavours. We show that the Goldstone boson exchange model gives results at variance with one-gluon-exchange models.
