Dijet production as a centrality trigger for p-p collisions at CERN LHC

L. Frankfurt, M. Strikman, C. Weiss

We demonstrate that a trigger on hard dijet production at small rapidities allows to establish a quantitative distinction between central and peripheral collisions in pbar-p and p-…

Chiral-Odd Fragmentation Functions in Single Pion Inclusive Electroproduction

Leonard P. Gamberg, Dae Sung Hwang, Karo A. Oganessyan

We consider a sub-leading twist chiral-odd pion fragmentation function and explore its contribution in single pion semi-inclusive electroproduction. We evaluate the single beam-spi…

Novel Transversity Properties in SIDIS

Leonard Gamberg, Gary R. Goldstein, Karo A. Oganessyan

We consider a rescattering mechanism to calculate a leading twist -odd pion fragmentation function, a candidate for filtering the transversity properties of the nucleon. We eval…

The Effects of Quantum Entropy on the Bag Constant

David E. Miller, Abdel-Nasser Tawfik

The effects of quantum entropy on the bag constant are studied at low temperatures and small chemical potentials. The inclusion of the quantum entropy of the quarks in the equation…

Determining the Proximity of Γ^{\ast} N Scattering to the Black Body Limit Using DIS and J/ ψProduction

T. Rogers, V. Guzey, M. Strikman +1

We use information about DIS and production on hydrogen to model the -dependence of the scattering amplitude. We investigate the profile function for elastic…

DVCS on nuclei: Observability and Consequences

A. Freund, M. Strikman

In this paper, we discuss the feasibility of measuring deeply virtual Compton scattering (DVCS) on nuclei in a collider setting, as for example, the planned high-luminosity Electro…

Chiral dynamics and the growth of the nucleon's gluonic transverse size at small x

M. Strikman, C. Weiss

We study the distribution of gluons in transverse space in the nucleon at moderately small x (~10^{-2}). At large transverse distances (impact parameters) the gluon density is gene…

Leading twist coherent diffraction on nuclei in deep inelastic scattering at small x and nuclear shadowing

L. Frankfurt, V. Guzey, M. Strikman

We extend the theory of leading twist nuclear shadowing to calculate leading twist nuclear diffractive parton distribution functions (nDPDFs). We observe that the quark and gluon n…

Entropy for Quark States

David E. Miller

We discuss the quantum state structure using the standard model for three colored quarks in the fundamental representations of making up the singlet ground state of the h…

A mechanism for the T-odd pion fragmentation function

Leonard P. Gamberg, Gary R. Goldstein, Karo A. Oganessyan

We consider a simple rescattering mechanism to calculate a leading twist -odd pion fragmentation function, a favored candidate for filtering the transversity properties of the n…

Measurement of tan beta in associated t H^\pm Production in gamma gamma Collisions

M. A. Doncheski, Stephen Godfrey, Shouhua Zhu

The ratio of neutral Higgs field vacuum expectation values, tan beta, is one of the most important parameters to determine in type-II Two-Higgs Doublet Models (2HDM), specifically…

Coherent Photoproduction from Nuclei

L. Frankfurt, M. Strikman, M. Zhalov

We argue that study of the cross section of coherent photo(electro) production of vector mesons off nuclear targets provides an effective method to probe the leading twist hard QCD…

Onset of Perturbative Color Opacity at Small x and Upsilon Coherent Photoproduction off heavy nuclei at LHC

L. Frankfurt, V. Guzey, M. Strikman +1

We study photon-induced coherent production of Upsilon in ultraperipheral heavy ion collisions at LHC and demonstrate that the counting rates will be sufficient to measure nuclear…

The universal psi-prime-prime to psi-prime ratio as unambiguous signature for hard physics in nuclear reactions and in decays of beauty hadrons

L. Frankfurt, L. Gerland, M. Strikman +1

We suggest the ratio of the production cross sections as an unambiguous probe of the dominance of hard, point-like physics in charmonium production. If hard ph…

Novel Transversity Properties in Semi-Inclusive Deep Inelastic Scattering

Leonard P. Gamberg, Gary R. Goldstein, Karo A. Oganessyan

The -odd distribution functions contributing to transversity properties of the nucleon and their role in fueling nontrivial contributions to azimuthal asymmetries in semi-inclus…
