Seeing Through the Nucleus: A Review of Color Transparency Phenomena Open
We review the current status of the phenomenon of Color Transparency (CT), a fundamental consequence of the description of hadrons from Quantum Chromo Dynamics. CT refers to the vanishing of final (and/or initial) state interactions with t…

High precision measurement of phi-nucleon cross section using a tensor polarized deuteron target Open
We propose to measure the $ϕ$-nucleon cross section $σ_{ϕN}$ to solve the longstanding puzzle of whether $σ_{ϕN} \simeq 10$ mb, as extracted from photoproduction, or $\sim$30 mb, as obtained from nuclear rescattering. CLAS data demonstrate…

Pion Valence Structure at Intermediate x in the Residual Field Model Open
We calculate the valence parton distribution function of the pion, for the range of $0.1 \le x \le 0.6$, based on the soft dynamics of the partons within the valence-residual field model. Within this model we assume that the soft partonic …

Hole in the Deuteron Open
We introduce a new observable, $A_{node}$, that allows to isolate the node in the S-partial wave distribution of the deuteron in high $Q^2$ electro-disintegration processes with tensor polarized target. The node is a signature of nuclear r…

Non-nucleonic degrees of freedom and the spin structure of the deuteron Open
Electro-disintegration of the deuteron at large $Q^2$ currently represents on of the most promising reactions which allows to probe the bound nuclear state at internal momenta comparable to the rest mass of the nucleon. Large internal mome…

Examining the evolution of the maximum of valence quark distribution, qV, weighted by Bjorken x, h(x,t)≡xqV(x,t), it is observed that h(x,t) at the peak becomes a one-parameter function; h(xp,t)=Φ(xp(t)), where xp is the position of the pe…
