Hadron Optics in Three-Dimensional Invariant Coordinate Space from Deeply Virtual Compton Scattering

S. J. Brodsky, D. Chakrabarti, A. Harindranath +2

The Fourier transform of the deeply virtual Compton scattering amplitude (DVCS) with respect to the skewness parameter ζ= Q^2/ 2 p.q can be used to provide an image of the target h…

Vacuum self-focussing of very intense laser beams

Dmitri Kharzeev, Kirill Tuchin

We argue that long-range photon-photon attraction induced by the dipole interaction of two electron-positron loops can lead to "vacuum self-focussing" of very intense laser beams.…

Light Higgs Production in Hyperon Decay

Xiao-Gang He, Jusak Tandean, G. Valencia

A recent HyperCP observation of three events in the decay Sigma^+ -> p mu^+ mu^- is suggestive of a new particle with mass 214.3 MeV. In order to confront models that contain a lig…

Single transverse-spin asymmetry in high transverse momentum pion production in pp collisions

Chris Kouvaris, Jian-Wei Qiu, Werner Vogelsang +1

We study the single-spin (left-right) asymmetry in single-inclusive pion production in hadronic scattering. This asymmetry is power-suppressed in the transverse momentum of the pro…

Coherent multiple scattering effect in DIS

Xiaofeng Guo, Jun Li

We present a QCD calculation of the coherent multiple scattering effect on single hadron production in semi-inclusive lepton-nucleus deep inelastic scattering (DIS). We show that t…

NRQCD Factorization and Velocity-dependence of NNLO Poles in Heavy Quarkonium Production

Gouranga C. Nayak, Jian-Wei Qiu, George Sterman

We study the transition of a heavy quark pair from octet to singlet color configurations at next-to-next-to-leading order (NNLO) in heavy quarkonium production. We show that the in…

Open charm tomography of cold nuclear matter

I. Vitev, T. Goldman, M. B. Johnson +1

We study the relative contribution of partonic sub-processes to D meson production and D meson-triggered inclusive di-hadrons to lowest order in perturbative QCD. While gluon fusio…
