Off - diagonal quark distribution functions of the pion within an effective single instanton approximation

We develop a relativistic quark model for hadron structure which, incorporates the non-trivial structure of the vacuum of Quantum Chromodynamics as modelled by instantons, and is defined taking properly into account gauge invariance. Hadrons are boundstates of quarks and the strong quark-hadron vertices are determined from an instanton induced effective lagrangian. The parameters of the model, ...

0 Off - diagonal quark distribution functions of the pion within an effective single instanton approximation

We develop a relativistic quark model for pion structure, which incorporates the non-trivial structure of the vacuum of Quantum Chromodynamics as modelled by instantons. Pions are boundstates of quarks and the strong quark-pion vertex is determined from an instanton induced effective lagrangian. The interaction of the constituents of the pion with the external electromagnetic field is introduce...

Single Spin Asymmetry In Inclusive Pion Production ∗

It is shown how the single spin asymmetry observed in inclusive pion production is related, in the helicity basis, to the imaginary part of the product of two different distribution amplitudes, rather than to the usual quark and gluon distribution functions; there is then no reason why it should be zero even in massless perturbative QCD, provided the quark intrinsic motion is taken into account...

Improved master equation approach to quantum transport: from Born to self-consistent Born approximation.

Beyond the second-order Born approximation, we propose an improved master equation approach to quantum transport under self-consistent Born approximation. The basic idea is to replace the free Green's function in the tunneling self-energy diagram by an effective reduced propagator under the Born approximation. This simple modification has remarkable consequences. It not only recovers the exact ...

Effective Born radii in the generalized Born approximation: The importance of being perfect

Generalized Born (GB) models provide, for many applications, an accurate and computationally facile estimate of the electrostatic contribution to aqueous solvation. The GB models involve two main types of approximations relative to the Poisson equation (PE) theory on which they are based. First, the self-energy contributions of individual atoms are estimated and expressed as "effective Born rad...
