In the framework of the SU(3) chiral quark model, the S−wave baryon-baryon bound states are investigated. It is found that according to the symmetry character of the system and the contributions from chiral fields, there are three types of bound states. The states of the first type, such as [ΩΩ] (0,0) and [Ξ * Ω] (0,1/2) are deeply bound dibaryon with narrow widths. The second type states, [Σ *...

We derive the Bethe Ansatz Equations on the half line for particles interacting through factorized S-matrices invariant relative to the centrally extended su(2|2) Lie superalgebra and su(1|2) open boundaries. These equations may be of relevance for the study of the spectrum of open strings on AdS5×S 5 background attached to Y = 0 giant graviton branes. An one-dimensional spin chain hamiltonian ...

1. Introdu tion Many di erent topi s in mathemati s, ranging from applied subje ts su h as optimization to pure areas su h as arrangements of hyperplanes, naturally lead to matroids. The approa h we will explore is matroid theory as an abstra tion of aÆne and proje tive geometry. Therefore the rst several se tions will survey some elementary, although perhaps unfamiliar, aspe ts of geometry. We...

SAŽETAK: Osnivanje šumskih kultura u Hrvatskoj započelo je sedamdesetih godina 20. stoljeća. Otada je udio šumskih kultura u šumskom fondu Hrva t ske varirao tijekom godina, a danas iznosi oko 3 %. Nove znanstvene spozna je ukazuju na postojanje opravdanih razloga daljnjeg te povećanog os nivanja šumskih kultura u Hrvatskoj (posebice spontano povećanje prikladnih površina za njihovo osnivanje)....

A method based on flavour SU(3) is proposed for identifying and extracting New Physics (NP) amplitudes in charmless ∆S = 1 Bs decays using time-dependent CP asymmetries in these decays and in flavour SU(3) related ∆S = 0 decays. For illustration, we assume a hierarchy, ∼ 1 : λ : λ (λ = 0.2), between a dominant ∆S = 1 penguin amplitude, a NP amplitude and a Standard Model amplitude with weak pha...

Let X = H/L be an irreducible real bounded symmetric domain realized as a real form in an Hermitian symmetric domain D = G/K. The intersection S of the Shilov boundary of D with X defines a distinguished subset of the topological boundary of X and is invariant under H and can also be realized as S = H/P for certain parabolic subgroup P of H . We study the spherical representations Ind P (λ) of ...

In the recently proposed dark left-right gauge model (DLRM) of particle interactions, the usual left-handed lepton doublet (ν, e)L transforming under SU(2)L is accompanied by the unusual right-handed fermion doublet (n, e)R transforming under SU(2)R, where nR is not the Dirac mass partner of νL. In this scenario, whereas νL is certainly a neutrino, nR should be considered a scotino, i.e. a dark...

The main purpose of the study is determination of the pollutants hazard potential as well as environmental vulnerability of Qarah Su River. First the most significant pollutant sources in the Qarah Su river watershed were identified and then accordingly the pollution hazard potential rate was calculated in Universal Ranking System Model setting. Then, by generalizing the algebraic sum of the re...

We consider both closed and open integrable antiferromagnetic chains constructed with the SU(N )-invariant R matrix. For the closed chain, we extend the analyses of Sutherland and Kulish – Reshetikhin by considering also complex “string” solutions of the Bethe Ansatz equations. Such solutions are essential to describe general multiparticle excited states. We also explicitly determine the SU(N )...
