Structure functions for the three nucleon system

F. Bissey, A. W. Thomas, I. R. Afnan

The spectral functions and light-cone momentum distributions of protons and neutrons in 3He and 3H are given in terms of the three-nucleon wave function for realistic nucleon-nucle…

Supersymmetric penguin contributions to the decay b -> s gamma with non-universal squarks masses

M. B. Causse, J. Orloff

We give explicit expressions for the amplitudes associated with the supersymmetric contributions to the process: b -> s gamma in the context of SUSY extensions of Standard Model wi…

The reaction dynamics of the 16O(e,e'p) cross section at high missing energies

Jefferson Lab Hall A Collaboration, N. Liyanage

We measured the cross section and response functions (R_L, R_T, and R_LT) for the 16O(e,e'p) reaction in quasielastic kinematics for missing energies 25 <= E_miss <= 120 MeV at var…

Some Remarks about Duality, Analytic Torsion and Gaussian Integration in Antisymmetric Field Theories

Alexander Cardona

From a path integral point of view (e.g. \cite{Q98}) physicists have shown how {\it duality} in antisymmetric quantum field theories on a closed space-time manifold relies in a…

Curvature on determinant bundles and first Chern forms

Sylvie Paycha, Steven Rosenberg

The Quillen-Bismut-Freed construction associates a determinant line bundle with connection to an infinite dimensional super vector bundle with a family of Dirac-type operators. We…

Enhanced Direct CP Violation in

X. -H. Guo, O. Leitner, A. W. Thomas

We study direct CP violation in the hadronic decay , including the effect of mixing. We find that the CP violating asymmetry is strongly dependent…

Deep inelastic scattering on asymmetric nuclei

K. Saito, C. Boros, K. Tsushima +3

We study deep inelastic scattering on isospin asymmetric nuclei. In particular, the difference of the nuclear structure functions and the Gottfried sum rule for the lightest mirror…

Transition from in-plane to out-of-plane azimuthal enhancement in Au+Au collisions

A. Andronic, G. Stoicea, M. Petrovici +1

The incident energy at which the azimuthal distributions in semi-central heavy ion collisions change from in-plane to out-of-plane enhancement, E_tran, is studied as a function of…

The first determination of Generalized Polarizabilities of the proton by a Virtual Compton Scattering experiment

The VCS, A1 collaboration

Absolute differential cross sections for the reaction (e+p -> e+p+gamma) have been measured at a four-momentum transfer with virtuality Q^2=0.33 GeV^2 and polarization ε= 0.62 in t…

Neutron Structure Function and A=3 Mirror Nuclei

I. R. Afnan, F. Bissey, J. Gomez +4

We investigate deep inelastic scattering from He-3 and H-3 within a conventional convolution treatment of binding and Fermi motion effects. Using realistic Faddeev wave functions t…

Changing shapes in the nanoworld

Nicolas Combe, Pablo Jensen, Alberto Pimpinelli

What are the mechanisms leading to the shape relaxation of three dimensional crystallites ? Kinetic Monte Carlo simulations of fcc clusters show that the usual theories of equilibr…

Duality in the non-relativistic harmonic oscillator quark model in the Shifman-Voloshin limit : a pedagogical example

A. Le Yaouanc, D. Melikhov, V. Morenas +3

The detailed way in which duality between sum of exclusive states and the free quark model description operates in semileptonic total decay widths, is analysed. It is made very exp…
