The nucleon axial mass and the MiniBooNE Quasielastic Neutrino-Nucleus Scattering problem
nucleon axial mass MiniBooNE Quasielastic Neutrino-Nucleus Scattering problem
2011/7/21
The charged-current double differential neutrino cross section, measured by the MiniBooNE Collaboration, has been analyzed using a microscopical model that accounts for, among other nuclear effects, l...
Direct Photon Production in Proton-Nucleus and Nucleus-Nucleus Collisions
direct photons nuclear suppression gluon shadowing
2011/7/21
Prompt photons produced in a hard reaction are not accompanied with any final state interaction, either energy loss or absorption. Therefore, besides the Cronin enhancement at medium transverse moment...
Low energy ω(\to π^0 γ) meson photoproduction in the nucleus
ω meson photoproduction π0γ invariant mass distribution
2011/7/20
The $\pi^0 \gamma$ invariant mass distribution spectra in the $ (\gamma, \pi^0\gamma) $ reaction were measured by TAPS/ELSA collaboration to look for the hadron parameters of the $\omega$ meson in Nb ...
Mach-like emission from nucleon scattering in proton-nucleus reaction
nucleon scattering proton-nucleus reaction
2011/7/20
The fast-stage nucleon emission of proton-nucleus (pA) reactions from 300A MeV to 1.8A GeV has been investigated using the quantum molecular-dynamics model.
Proton inelastic diffraction by a black nucleus and the size of excited nuclei
black nucleus Proton inelastic diffraction
2011/7/20
We systematically derive a length scale characterizing the size of a low-lying, beta stable nucleus from empirical data for the diffraction peak angle in the proton inelastic differential cross sectio...
Strangeness Production close to Threshold in Proton-Nucleus and Heavy-Ion Collisions
Production close to Threshold Proton-Nucleus Heavy-Ion Collisions
2011/7/20
We discuss strangeness production close to threshold in p+A and A+A collision. Comparing the body of available K+, K0, K-, and Lambda data with the IQMD transport code and for some key observables as ...

2011/1/4
High-spin states in the odd-odd nucleus $^{168}$Ta have been populated in the $^{120}$Sn($^{51}$V,3n) reaction. Two multi-quasiparticle structures have been extended significantly from spin $\sim{20\h...
The experimental data of the COSY-GEM collaboration for the recoil-free transfer reaction p(27Al,3He)π−p′X, leading to the formation of bound state of eta (η) meson in 25Mg nucleus, is reanalyze...
Variational and perturbative approaches to the confined hydrogen atom with a moving nucleus
