We show that energetically favored meson-baryon fluctuations present in the light-cone wavefunction of a transversely polarized proton can account for the left-right asymmetries measured in inclusive meson production processes.

Azimuthal single-spin asymmetries (SSA) in semi-inclusive electroproduction of charged pions and kaons in deep-inelastic scattering of positrons on a transversely polarised hydrogen target were observed. SSA amplitudes for both the Collins and the Sivers mechanism are presented.

The tensor charges of the nucleon are calculated in the framework of the SU(3) chiral quark soliton model. The rotational 1/Nc and strange quark mass corrections are taken into account up to linear order. We obtain the following numerical values of the tensor charges: δu = 1.12, δd = −0.42, and δs = −0.008. In contrast to the axial charges, the tensor charges in our model are closer to those of...

There may be differences between this version and the published version. You are advised to consult the publisher's version if you wish to cite from it. 2 We report the measurement of beam-target double-spin asymmetries (ALT) in the inclusive production of identified hadrons, e + 3 He ↑ → h + X, using a longitudinally polarized 5.9 GeV electron beam and a transversely polarized 3 He target. Had...

A position sensitive detector (PSD) is frequently used for the measurement of a one-dimensional position along a line or a two-dimensional position on a plane, but is more often used for measuring static or quasi-static positions. Along with its quick response when measuring short time-spans in the micro-second realm, a PSD is also capable of detecting the dynamic positions of moving objects. I...

New results on single spin asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarised LiD target are presented. The data were taken in the years 2002, 2003 and 2004 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. Preliminary results are given for the Sivers asymmetry and for all the three “quark polarimeters” present...

A finely layered medium behaves as a homogeneous anisotropic medium at long wavelengths. When each layer is a transversely isotropic viscoelastic (TIV) medium, attenuation anisotropy can be described by a generalization of Backus averaging to the lossy case. We introduce a method to compute the complex and frequency-dependent stiffnesses of the equivalent viscoelastic, homogeneous, transversely...

This paper is concerned with the effective piezoelectric moduli of a special class of dispersions called matrix laminates composites that are known to possess extremal elastic and dielectric moduli. It is assumed that the matrix material is an isotropic dielectric, and the inclusions and composites are transversely isotropic piezoelectrics that share the same axis of symmetry. The exact express...

The governing equations of a transversely isotropic dissipative medium are solved analytically to obtain the surface wave solutions. The appropriate solutions satisfy the required boundary conditions at the stress-free surface to obtain the frequency equation of Rayleigh wave. The numerical values of the non-dimensional speed of Rayleigh wave speed are computed for different values of frequency...

This paper discusses a detailed study carried out on vibration characteristics of transversely loaded pultruted composite beams. A considerable discrepancy was noticed in the measured vibration of the transversely loaded beam and the calculated natural frequencies of the beam using Euler-Bernoulli beam theory. It has been observed that the natural frequencies of the beam were increased after la...
