Systematics of Angular and Pol 4 Rization Di ~ Stributions Ix Three Body Decays

چکیده
A general method is proposed for the measurement of the polarization and alignment of a particle of arbitrary spin from the analysis of its three body decays. This method provides a procedure for the determination of spin and parity of the decaying system which is independent of the dynamics of the decay process.. The procedure is closely related to the one currently used for two-body reactions except that the normal to the decay-plane replaces the center-of-mass momentum as an analyzer. The general formalism is developed and illustrated by two examples; three pion decays and baryon-two pion decays. (Submitted to The Physical Review) I *Work supported by U. S.

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
متن کاملLife history traits and gonad histology of an endemic cyprinid fish, Mond spotted barb, Capoeta mandica from Southern Iran
The life history traits and gonad development of an endemic cyprinid fish, the spotted barb, Capoeta mandica (Bianco & Banarescu 1982), from southern Iran was investigated by regular monthly collections from February 2006 through January 2007 and on the basis of microscopic and macroscopic analyses. No information on the spawning characteristics of the fish are available to date. A total of 335...
متن کاملLinear dynamic response of nanobeams accounting for higher gradient effects
Linear dynamic response of simply supported nanobeams subjected to a variable axial force is assessed by Galerkin numerical approach. Constitutive behavior is described by three functional forms of elastic energy densities enclosing nonlocal and strain gradient effects and their combination. Linear stationary dynamics of nanobeams is modulated by an axial force which controls the global stiffne...
متن کاملContribution to the molecular systematics of the genus Capoeta from the south Caspian Sea basin using mitochondrial cytochrome b sequences (Teleostei: Cyprinidae)
Traditionally, Capoeta populations from the southern Caspian Sea basin have been considered as Capoeta capoeta gracilis. Study on the phylogenetic relationship of Capoeta species using mitochondrial cytochrome b gene sequences show that Capoeta population from the southern Caspian Sea basin is distinct species and receive well support (posterior probability of 100%). Based on the tree topologie...
متن کاملSystematics of Large Axial Vector Meson Production in Heavy Flavor Weak Decays
Large branching ratios observed for D and B decays to final states containing the a1(1260) ± are comparable to those for corresponding decays to states containing a charged pion or a charged ρ, and much larger than those for all other decays. Implications are discussed of a “vector-dominance model” in which a W is produced and immediately turns into an axial vector, vector or pseudoscalar meson...
