Exotic penta-quark baryon with strangeness +1, Θ, is studied in the QCD sum rule approach. We derive sum rules for the positive and negative parity baryon states with J = 1 2 and I = 0. It is found that the standard values of the QCD condensates predict a negative parity Θ of mass ≃ 1.5 GeV, while no positive parity state is found. We stress the roles of chiral-odd condensates in determining th...

A time series of mean weekly sea surface temperature (SST) images was used to investigate the relationship between ̄uctuations in the marine survival of hatchery-reared coho salmon and coastal ocean dynamics off the north-western United States (51° to 37°N) between 1985 and 1996, using univariate and nonlinear bivariate regression analysis. Ocean conditions were matched against survival for a n...

we study the theory of best approximation in tensor product and the direct sum of some lattice normed spacesx_{i}. we introduce quasi tensor product space anddiscuss about the relation between tensor product space and thisnew space which we denote it by x boxtimesy. we investigate best approximation in direct sum of lattice normed spaces by elements which are not necessarily downwardor upward a...

Given a sequence Q of n numbers positive and negative the maximum subsequence of Q is the contiguous subsequence that has the maximum sum among all contiguous subsequences of Q Given a two dimensional array A of n n numbers positive and negative the maximum subarray of A is the contiguous subarray that has the maximum sum among all contiguous subarrays of A We present two O log n time parallel ...

Abstract We consider how to calculate the probability that the sum of the product of variables assessed with a Normal distribution is negative. The analysis is motivated by a specific problem in electrical engineering. To resolve the problem, two distinct steps are required. First, we consider ways in which we can assess the distribution for the product of two Normally distributed variables. Th...

The masses of the flavor octet and singlet baryons with negative parity and spin 1 2 are calculated using the QCD sum rule. We find that the chiral symmetry breaking vacuum condensates cause the mass splitting of the positive and negative baryons. The present sum rule reproduces the observed masses of these baryons within 10%, and predicts the mass of the excited Ξ baryon with J P = 1 2 − at 1....
