Generalized parton distributions and the parton structure of light nuclei
Generalized parton distributions parton structure of light nuclei

2011/1/6
The measurement of nuclear Generalized Parton Distributions (GPDs)represents a valuable tool to understand the structure of bound nucleons and the phenomenology of hard scattering off nuclei. By using...
Novel charmonium-like structures in the $J/\psi\phi$ and $J/\psi\omega$ invariant mass spectra
Novel charmonium-like structures
font style='font-size:12px;'>
2011/1/7
Stimulated by the new evidence of Y(4274) observed in the J/ invariant mass spectrum, we first propose the charmonium-like state Y(4274) as the S-wave Ds ¯D s0(2317) + h.c. molecular state with...

2011/1/6
Using, for the first time, configuration-constrained potential-energy-surface calculations with the inclusion of 6 deformation, we find remarkable effects of the high order deformation on the high-K ...
The "Ridge" in Proton-Proton Scattering at 7 TeV
"Ridge" Proton-Proton Scattering
font style='font-size:12px;'>
2011/1/7
We show that a hydrodynamical expansion leads in a natural way to the observed “ridge” structure in the two particle correlation function versus the pseudorapidity difference and the azimuthal angl...
Structure of low-lying quadrupole states in nuclei near 132Sn
Structure of low-lying quadrupole states nuclei near 132Sn
font style='font-size:12px;'>
2011/1/6
The properties of the low-lying 2+ states in the even-even nuclei around 132Sn are studied within the quasiparticle random phase approximation. Start-ing from a Skyrme interaction in the particle-hole...
New ways to access the transverse spin content of the nucleon
New ways transverse spin content of the nucleon
font style='font-size:12px;'>
2011/1/5
We first describe a new way to access the chiral odd transversity parton distribution in the proton through the photoproduction of lepton pairs. The basic ingredient is the interference of the usual B...
Challenges for Modeling Nuclear Structure: Are the Proton and Neutron Masses and A-body Interactions Relevant?
Modeling Nuclear Structure A-body Interactions Relevant
font style='font-size:12px;'>
2011/1/7
We discuss some of the challenges that future nuclear modeling may face in order to improve the description of the nuclear structure. One challenge is related to the need for A-body nuclear interactio...

2010/11/25
The high cost and scarcity of Pt pose serious problems for the widespread commercialization of fuel cell technologics.1 Recently, Pd-based cathode catalysts have attracted much attention because Pd po...
On the effect of multiplicative noise in a supercritical pitchfork bifurcation
multiplicative noise supercritical pitchfork bifurcation
font style='font-size:12px;'>
2010/4/21
The most important characteristic of {\em multiplicative noise} is that its effects of system's dynamics depends on the recent system's state. Consideration of multiplicative noise on self-referential...
Antihydrogen formation dynamics in a multipolar neutral anti-atom trap
Antihydrogen CPT Non-Neutral Plasma Particle Transport

2010/3/15
Antihydrogen production in a neutral atom trap formed by an octupole-based magnetic field minimum is demonstrated using field-ionization of weakly bound anti-atoms. Using our unique annihilation imagi...

2010/3/15
The scalar meson f_0(1370) - indicated in particular in the low energy p\bar p \to 3 body reactions - is a crucial element in certain schemes of the scalar meson spectroscopy including glueballs. The ...
