Unlike other examples of fermion pair production in e+e− collisions, we show that top-quark pairs are produced in an essentially unique spin configuration in polarized e+e− colliders at all energies. Since the directions of the electroweak decay products of polarized top-quarks are strongly correlated to the top-quark spin axis, this unique spin configuration leads to a distinctive topology for...

We postulate that the orientation of the soft supersymmetry-breaking terms in flavor space is not fixed by tree level physics at the Planck scale; it is a dynamical variable which depends on fields that have no tree level potential. These fields can be thought of as either moduli or as the Nambu-Goldstone bosons of the spontaneously broken flavor symmetry which is non-linearly realized by the s...

Probably not. PACS numbers: 03.65.Ta, 03.65.Xp, 14.60.Pq If recent measurements [1] suggesting that neutrinos travel faster than light survive scrutiny, the question of their theoretical interpretation will arise. Here we discuss the possibility that the apparent superluminality is a quantum interference effect, that can be interpreted as a weak measurement [2–5]. Although the available numbers...

In this paper, we examine the behaviour of so-called passive and middle aorist forms in Greek reflected Genesis Septuagint. The Septuagint, Biblical more generally, displays a considerable aberration with respect to other varieties Ancient regarding relative frequency vis-à-vis forms. Here, explore feature Septuagint some detail, showing that there is or less consistent, binary system at stage,...

A complete set of inequivalent realizations of threeand four-dimensional real unsolvable Lie algebras in vector fields on a space of an arbitrary (finite) number of variables is obtained. Representations of Lie algebras by vector fields are widely applicable e.g. in integrating of ordinary differential equations, group classification of partial differential equations, the theory of differential...

We use the microscopic instanton calculus to determine the one-instanton contribution to the quantum modulus u3 = 〈Tr(φ3)〉 in N = 2 SU(Nc) supersymmetric QCD with Nf < 2Nc fundamental flavors. This is compared with the corresponding prediction of the hyperelliptic curves which are expected to give exact solutions in this theory. The results agree up to certain regular terms which appear when Nf...

extended abstract 1. introduction mazinan, a village and the center of a rural district, is a subdivision of sabzevar city located in the eastern part of razavi-khorasan province. the fact that this village has been mentioned and described as a cultivated town in hodud al-alam men al-mašriq ila l-maqrib (see sotudeh, 1983) written in the10th century a.d. indicates that mazinan is at least15 cen...

Let R be a ring with center Z, Jacobson radical J , and set N of all nilpotent elements. Call R generalized periodic-like if for all x ∈ R \ (N ∪ J ∪ Z) there exist positive integers m, n of opposite parity for which xm − xn ∈ N ∩ Z. We identify some basic properties of such rings and prove some results on commutativity. Let R be a ring; and let N = N(R), Z = Z(R) and J = J(R) denote respective...

We analyze changes of the Immirzi parameter in loop quantum gravity and compare their consequences with those of Lorentz boosts and constant conformal transformations in black hole physics. We show that the effective value deduced for the Planck length in local measurements of vacuum black holes by an asymptotic observer may depend on its conformal or Lorentz frame. This introduces an apparent ...

the district of miyān kūh in the ardal town,chahār mahāl bakhtiari province, because of its high mountains, deep valleys and the fields among small mounts, being placed in the path of the was dering tribes has been the focus of the attention. the rigion has two different viewpoint. one part featuring the mounts chēhēl cheshme and gereh with the altitude of more than 3500 m., has cold winter and...
