We argue that the experimentally measured color transparency ratio is directly related to the interacting hadron wave function at small transverse separation, b < 1/Q. We show that the present experimental data is consistent with pure scaling behavior of the hadron-hadron and lepton-hadron scattering inside the nuclear medium.

Hadron spectroscopy on dynamical configurations are faced with the difficulties of dealing with the mixing of single particle states and multi-hadron states (for large spatial volumes and light dynamical quarks masses). It is conceivable that explicit multi-hadron interpolating operators will be necessary for obtaining sufficiently good overlap on to multi-hadron states in order to extract the ...

Universality says that the mechanisms of hadron production are the same in all high-energy processes in which most of the final state hadrons arise from hard or semi-hard scattering of partons. Differences in the detailed composition of the final states are assumed to be due to differences in the flavours and configurations of the initial partons. Perturbative quantum chromodynamics (pQCD) has ...

We present a picture of confinement based on representation of quarks as pointlike topological defects. The topological charge carried by quarks and confined in hadrons is explicitly constructed in terms of Yang-Mills variables. In 2+1 dimensions we are able to construct a local complex scalar field V (x), in terms of which the topological charge is Q = − i 4π d 2 xǫ ij ∂ i (V * ∂ i V − c.c.). ...
