Fundamental interactions

Fundamental Symmetries and Interactions

In nuclear physics numerous possibilities exist to investigate fundamental symmetries and interactions. In particular, the precise measurements of properties of fundamental fermions, searches for new interactions in β-decays, and violations of discrete symmeties offer possibilities to search for physics beyond standard theory. Precise measurements of fundamental constants can be carried out. Lo...

and Unification of Fundamental Interactions

representing the CDF and D0 collaborations ABSTRACT The Tevatron Run-II program has been in progress since 2001, and the CDF and D0 experiments have been operational with upgraded detectors. Coupled with recent improvements in the Tevatron accelerator performance, the experiments have started producing important physics results and measurements. We report these measurements as well as prospects...

Unified Theory of Fundamental Interactions

Based on local gauge invariance, four different kinds of fundamental interactions in Nature are unified in a theory which has SU(3)c⊗SU(2)L⊗U(1)⊗s Gravitational Gauge Group gauge symmetry. In this approach, gravitational field, like electromagnetic field, intermediate gauge field and gluon field, is represented by gauge potential. Four kinds of fundamental interactions are formulated in the sim...

Unification of Fundamental Interactions in Supersymmetry

A review is given of recent developments on the implications of supergravity grand unification with SU(5)-type proton decay under the condition MH3/mG < 10 (where MH3 is the Higgs triplet mass) and the naturalness condition that the universal scalar mass m0 and the gluino mass are < 1 TeV. It is shown that the maximum achievable lifetime limits on proton lifetime at Super Kamiokande and ICARUS ...
