Polarization Phenomena and Composite Structure of Hadrons

Phenomena Nd the Short Distance Structure of Hadrons

In certain cases, nuclear corrections to hadronic phenomena depend in detail on the nature of quark and gluon interactions, as well as the effects of jet development within the nuclear medium. In this talk I review applications of quantum chromodynamics to fast particle production in nuclear collisions, nuclear form factors, and shadowing in deep inelastic lepton processes. I also discuss a new...

Composite Hadrons and Relativistic Nuclei

the underlying structure of language proficiency and the proficiency level

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...

Qcd Phenomena and the Light-cone Wavefunctions of Hadrons

Light-cone Fock-state wavefunctions encode the properties of a hadron in terms of its fundamental quark and gluon degrees of freedom. A recent experiment at Fermilab, E791, demonstrates that the color coherence and shape of light-cone wavefunctions in longitudinal momentum fraction can be directly measured by the high energy diffractive jet dissociation of hadrons on nuclei. Given the proton’s ...

Violation of s - Channel Helicity Conservation and Composite Structure of Hadrons

s-channel helicity conservation (SHC) for Pomeron exchanging amplitude was discovered empirically for rP----"PoP reaction, 1l and was suggested to hold also in the case of nN elastic scattering_"> Later analysis on nN scattering amplitudes,3> however, showed that the ratio, IF1_1f(IF~+i.J-T/s0 ), which may be considered as a barometer of the violation of SHC for I, =0 exchanging amplitudes, was...
