h£-S. Chen et al. / Diffractive production In general for the weak and electromagnetic currents J in the leptoproduction reactions e-p~e-pOp, up ~t-p+p, pp~ppOp, etc., one is studying the matrix element (V[J[O) for each vector meson into which the current can convert. Linear Vector Spaces and Cartesian Tensors is primarily concerned with the theory of finite dimensional Euclidian spaces. It makes a careful distinction between real and complex spaces, with an emphasis on real spaces, and focuses on those elements of the theory that are especially important in applications to continuum s: 3.

The inclusive production cross sections of η′ () andfo () mesons are measured ine+e− annihilation in the nonresonant continuum around s = 10 \sqrt s= 10 s = 1 0 GeV and in decays of the υ resonances using the ARGUS detector.

For η′ () mesons, a production ratio of η′ ()/ηdir=±, with ηdir=η−BR(η′→ηX)η′, is determined in direct υ(1S) decays. In hadronic Zo decays, inclusive production rates have been measured for a large number of meson and baryon states (see Ref.

[ 1 ] and references therein). However, up to now, the tensor meson f2() has been observed and studied only in exclusive reactions like K-p-4 f2A [2], J/tlr -+ fey [3] and yy -; f2 [4]. The description proposed here for the radiative decays is based on Vector Meson Dom-inance (VMD) model formulated by Sakurai in [10] and represented by the dia-grams in Fig.

Using the intermediate state with two vector mesons one can describe at least qualitatively the main features of the radiative decays. This approach fails how. Enhanced production of low-mass electron pairs in GeV/u S-AU collisions at the CERN-SPS*.

The study of hadronic decays using lattice tech-niques has long been known to be feasible in prin-ciple [1,2]. Pioneering attempts were made to study glueball decay [3] and ρmeson decay [4] in quenched QCD where no actual decay takes place. This un-derlines the approach: one can study the mixing of hadronic states on a lattice, provided that.

cuss b-quark production and current results on spectroscopy and lifetimes of b-flavored hadrons. We then discuss some ba-sic properties of B-meson decays, followed by summaries of hadronic, rare, and electroweak penguin decays of B-mesons.

There are separate mini-reviews for BB mixing [8] and the ex. In high energy physics, a vector meson is a meson with total spin 1 and odd parity (usually noted as J P = 1 −).Vector mesons have been seen in experiments since the s, and are well known for their spectroscopic pattern of masses.

The vector mesons contrast with the pseudovector mesons, which also have a total spin 1 but instead have even vector and pseudovector mesons are. B meson production and detection B meson decays have been studied at pp and e+e colliding beam facilities, operating at very different beam energies.

The e+ colliders operated at a fixed energy of GeV in the years to At this energy, about 20 MeV above the kinematic threshold for BB production, e+ and e annihilate and produce. The magnitude (or length) of a vector is denoted by a or a. It is a scalar and must be non-negative.

Any vector whose length is 1 is called a unit vector; unit vectors will usually be denoted by e. Figure (a) a vector; (b) addition of vectors Vector Algebra. A detailed study of vector meson production (ϕ and J/ψ) in e ± p collisions at HERA with the ZEUS and H1 detector has been performed.

The cross sections are measured as a function of Q 2, W and t. In this contribution, the results are summarised, compared to theoretical calculations and the dynamical picture emerging in perturbative QCD is highlighted.

We thus proceed as follows: the strange vector meson consists of two valence quarks (m l;m h). We compute the necessary observables (vector meson mass, vector decay constant and the ratio of the tensor to vector decay constant) for all combinations of am l.

Abstract. In the presence of the (), (), (), and () ± being the members of the meson multiplet, we investigate the mass spectrum of the meson state and the mixing angle of strange axial-vector mesons in the framework of meson-meson mass mixing and Regge phenomenology. Also, in the glueball dominance picture, the kaon is phenomenologically determined to have a mass of about.

We explore the decay of a vector meson to two pseudoscalar mesons on the lattice with Nf=2 flavours of sea quark. Although we are working with quark masses that do not allow a physical decay, we show how the transition rate can be evaluated from the amplitude for /ρ-->ππ and from the annihilation component of /ππ-->ππ.

We explore the decay amplitude for two different. Before getting into the subject of tensor product, let me first discuss “direct sum.” This is a way of getting a new big vector space from two (or more) smaller vector spaces in the simplest way one can imagine: you just line them up.

Space You start with two vector spaces, V that is n-dimensional, and W that is m-dimensional. The Identity Tensor. The linear transformation which transforms every tensor into itself is called the identity tensor. This special tensor is denoted by I so that, for example, Ia =a for any vector a.

In particular, Ie1=e1,Ie2=e2,Ie3=e3, from which it follows that, for a Cartesian coordinate system, I. magnitude and direction both, called Vector.

But certain quantities are associated with two or more directions, such a quantity is called Tensor. The stress at a point of an elastic solid is an example of a Tensor which depends on two directions one normal to the area and other that of the force on it. VECTOR AND TENSOR ANALYSIS.

Prior to our applying vector and tensor analysis to our research area of modern continuum mechanics, we almost had to relearn the subject.

Therefore, one of our objectives in writing this book is to make available a modern introductory textbook suitable for the first in-depth exposure to vectors and tensors. Lass's book, "Vector and Tensor Analysis," is an old classic in its field.
