We analyze the degree to which parity-violating ~PV! electroexcitation of the D(1232) resonance may be used to extract the weak neutral axial vector transition form factors. We find that the axial vector electroweak radiative ...

We show that a hydrodynamical model with continuous particle emission instead of sudden freeze out may explain both the observed strange particle and pion
abundances and transverse mass spectra for light projectile at SPS ...

The asymmetric tetrahedron is composed of all edges of a tetrahedron represented by Ising interactions except for one, which has a Heisenberg-type interaction. This asymmetric tetrahedron is arranged by connecting a vertex ...

Recognition of individual sea turtles is mostly achieved by checking artificial tags previously attached to them, a method which is made difficult by the considerable tag loss rate and which requires repeated manipulation ...

The principal objective of this paper is to offer a quantitative methodology for making forecasts to be used as an essential ingredient for MRP. The forecasts are for an individual product and for the very short-term, which ...

Models with essential non-perturbative QCD dynamics for the production of charmonium are extrapolated to give predictions of prompt J=Ã production at the LHC. Di®erences of up to an order of magnitude occurs, although the ...

We give an action for the massless spinning particle in pseudoclassical mechanics by using grassmann variables. The constructed action is invariant under _-reparametrizations, local SUSY and O(N) transformations. After ...

The transverse momentum distributions of hadrons in 200GeV Au-Au collisions at RHIC are calculated using the smoothed particle hydrodynamics code SPheRIO. They are compared with data from STAR and PHOBOS
Collaborations. ...

We define a coupling of two baker maps through a p=2 rotation both in position and in momentum. The classical trajectories thus exhibit spiraling, or loxodromic motion, which is only possible for conservative maps of at ...

The characteristic stretching and squeezing of chaotic motion is linearized within the finite number of phase space domains which subdivide a classical baker map. Tensor products of such maps are also chaotic, but a more ...

Quarkonium hadroproduction in association with a photon at high energies provides a probe of the dynamics of the strong interactions as it is dependent on the nuclear gluon distribution. Therefore, it could be used to ...

In a previous work we applied a discrete symmetry (Z' 2) in order to light fermions acquire mass only at one loop level. This symmetry and the assumption of alignment between fermions and sfermions allow us to avoid FCNC ...
