Particles and Fields

The concept of atoms has contributed greatly to the development of physics. Each element has its own atom. Atoms can bind together to form molecules or molecules can dissociate into atoms in chemical reactions, in which the identity of each atom is kept. Thus, it was thought that the atom is indivisible smallest unit of the element. The concept of atoms was well established through the study of...

( : : + WW,ZZ,HH,HW,HZ) and combine these results with those previously obtained for annihilation into fermions to find the relic cosmological abundance for the most general neutralino. The new channels are particularly important for Higgsino-like and mixed-state neutralinos, but are subdominant (to the fermion-antifermion annihilation channels) in the case that the neutralino is mostly a gaugi...

Massless Particles and Fields ”

Free fields of massless particles transforming covariantly under the Poincare group are constructed. The allowed infinite and finite dimensional representations of the Lorentz group are obtained. The wave functions are calculated in these representations in various bases u The commutation rules are computed, and turn out to be non-local for any infinite dimens ional fields. The transformation l...

Rapid Communications are intended for important new results which deserve accelerated publication, and are therefore given priority in editorial processing and production ARa.pid Communication in Physical Review D should be no longer than ftve printed pages and must be accompanied by an abstract. Page proofs are sent to authors, but because of the accelerated schedule, publication is generally ...
