Multiple Parton Scattering in Nuclei: Quark-quark Scattering
Modifications to quark and antiquark fragmentation functions due to quark-quark (antiquark) double scattering in nuclear medium are studied systematically up to order O(αs) in deeply inelastic scattering (DIS) off nuclear targets. At the order O(αs), twist-four contributions from quark-quark (antiquark) rescattering also exhibit the Landau-Pomeranchuck-Midgal (LPM) interference feature similar ...
متن کاملMultiple Parton Scattering in Nuclei Twist Four Nuclear Matrix Elements and O Forward Parton Distributions
Multiple parton scatterings inside a large nucleus generally involve higher twist nuclear parton matrix elements The gluon bremsstrahlung induced by multiple scattering depends not only on direct parton matrix elements but also on momentum crossed ones due to the Landau Pomeranchuk Migdal in terference e ect We show that both types of twist four nuclear parton matrix elements can be factorized ...

Multiple parton scatterings inside a large nucleus generally involve highertwist nuclear parton matrix elements. The gluon bremsstrahlung induced by multiple scattering depends not only on direct parton matrix elements but also on momentum-crossed ones, due to the Landau-Pomeranchuk-Migdal interference effect. We show that both types of twist-four nuclear parton matrix elements can be factorize...
متن کاملElastic Parton-Parton Scattering from AdS/CFT
Using the AdS/CFT correspondence and the eikonal approximation, we evaluate the elastic parton-parton scattering amplitude at large N and strong coupling gN in N=4 SYM. We obtain a scattering amplitude with a Regge behavior that unitarizes at large √ s. For partons with masses m in the range √ s > m > √ −t, we suggest that our results may be of relevance to QCD in four dimensions. E-mail: rho@s...
متن کاملNeutron scattering on nuclei.
Very small angle neutron scattering studies have been made on intact nuclei under a variety of solution conditions. Scattering maxima are observed at 30 to 40 nm and at 18 nm in most environments. Although the spacing, intensity and presence of the maximum near 40 nm varies considerably with environment the 18 nm is rather constant. The 30 to 40 nm maximum appears to be best interpreted by the ...
