Mirror fermions, J/Ψ particles, Kolar-mine events and neutrino anomaly

Abstract The role of colour and charm and heavy mirror fermions (suggested earlier in the context of a unification scheme) is explored in interpreting the J/ψ particles, the Kolar-mine events and the neutrino-antineutrino anomaly.

A preon model with hidden electric and magnetic type charges

Abstract The U(1) × U(1) binding forces in an earlier preonic composite model of quarks and leptons are interpreted as arising from hidden electric and magnetic type charges. The preons may possess intrinsic spin zero, the half-integer spins of the composites being contributed by the force field. The quark-lepton gauge symmetry is interpreted as an effective low-energy symmetry arising at the composite level. Some remarks are made regarding the possible composite nature of the graviton.

The recent single-tag two-photon experiments at petra and the issue of quark charges☆

Abstract The data of recent single-tag two-photon experiments indicating noticeable excess in ( R γγ ) jet over fractionally charged quark-parton model-predictions is studied from the point of view of its implications on the gauge integer charge quark model. Focusing attention on the region of p T exceeding about 3 GeV, where higher order QCD and non-perturbative effects might be expected to be small, it is noted that this excess and its Q 2 dependence can be attributed to the presence of a colour component in the electromagnetic current provided the effective mass of the gluon lies between about 150 to 350 MeV. Accurate measurements of R γγ in the high p T region ( p T ⪆ 5 GeV ) are crucial for an unambiguous distinction between fcq and gauge-icq models.

Charged Spin 1 Gluons, Parton Model and the Archimedes Effect

In a gauge theory of (SU(2)×U(1))flavour×SU(3)colour with un-confined integer-charged quarks and massive integer-charged gluons both quarks and gluons contribute to electro- and neutrino-production. The gluon parton contribution to the lepto-production of colour is considered.

THE MOON AS THE SEARCHING GROUND FOR PROTON DECAY

The distinct advantage which a lunar detector would have over a terrestrial one in searching for proton decays corresponding to rather long nucleon lifetimes ≳6×1032 yrs is noted.

Testing the family replication-model through B0B0 mixing

Abstract It is observed that the family-replication idea, proposed in the context of a minimal preon-model, necessarily implies a maximal mixing (i.e. ΔM ⪢ Γ) either in the Bs0 B s0 or the Bd0 B d0 system, in contrast to the standard model.

Natural left-right symmetry, atomic parity experiments and asymmetries in high energy e+e− collisions in petra and pep regions

Abstract The previously proposed left-right-symmetric SU (2) L × SU (2) R × U (1) theory permits one of the two neutral gauge particles N 1 and N 2 to be particularly light ( mW + L ) compatible with all neutrin-data and the present atomic parity experiments. Distinguishing features of this theory (with the light mass solution) for e − e + → μ + μ − and π + π − at PETRA and PEP energies as compared to the SU (2) × U (1) predictions are given.
