We calculate the decay couplings and first two Gegenbauer moments of the leading twist light-cone distribution amplitudes of K and K∗ from QCD sum rules, including NLO perturbative effects. Submitted to Physical Review D ∗[email protected] †[email protected]

We analyze the hyperon momentum distribution and correlation in (K−, K) reactions on C and Be targets. Both of K and Λ momentum distributions are well reproduced with the the IntraNuclear Cascade model followed by the statistical evaporation of Λ from hyperon compound nuclei. In the momentum correlation analysis of ΛΛ based on the model source functions, it is shown that strongly attractive ΛΛ ...

the two-spotted spider mite, tetranychus urticae koch (acari: tetranychidae), is an economically important pest of ornamental plant in iran. the population abundance and spatial distribution were studied on five rosa cultivars including maroussia, wendela, elderado, wenedetta, and hot lady during two growing seasons of 2011 and 2012 in greenhouse. the k parameter, index of dispersion, lloyd’s m...

Vitamin K group is known as an anti-haemorrhagic vitamin and has a common skeleton of 2-methyl-1,4-naphthoquinone. There are several homologs which differ in the alkyl side chain at 3-position of naphthoquinone ring. Of these homologs, vitamin K2(20) (K2) which has a geranyl-linalyl side chain is considered to be a physiologically active type of this vitamin, since Martius, et al.2) reported th...

parameter estimation is an important task in the modeling, classification, and detection of radar clutters. radar clutters have stochastic characteristics. therefore, statistical distributions are usually used to describe the features of clutters better. k distribution is one of the most common models utilized to the simulation of clutters. this distribution, which consists of scale and shape p...

three k-tree distance and fixed-sized plot designs were used for estimating tree density in sparse oak forests. these forests cover the main part of the zagros mountain area in western iran. they are non-timber-oriented forest but important for protection purposes. the main objective was to investigate the statistical performance of k-tree distance and fixed-sized plot designs in the estimation...
