The top quark found at long last
Article Abstract:
The top quark, a basic sub elementary particle, has been discovered at Fermilab by observing the decay products of particles formed in proton-antiproton collisions. The existence of top quark, though proposed theoretically several years earlier than its discovery could not be experimentally proved as it is the most massive of all the quarks. The discovery will enable nuclear and elementary particle physicists to develop new theories by experimentally investigating the top quark.

Classical and quantum physics mix
Article Abstract:
A physicist from Imperial College, London, UK, is developing a scheme to include the quantum and classical variables in a common theory to clear mathematical doubts regarding the coexistence of the variables in a single theory. The success of this effort will help understand the field theories of particle physics on the basis of the classical theory of gravity.

Making models of symmetry breaking
Article Abstract:
The breaking of symmetry, which occurs spontaneously in particle physics systems, is attributed to the dynamic and stochastic behavior of such systems. The systems are basically asymmetrical though they are superficially symmetrical. The breaking of symmetry in all macroscopic systems such as crystals occur at the electronic and protonic levels.
