Upper limits on the observational effects of nuclear pasta in neutron stars
relativity – gravitational waves – dense matter – stars neutron – stars
font style='font-size:12px;'>
2011/7/21
The effects of the existence of exotic nuclear shapes at the bottom of the neutron star inner crust - nuclear `pasta' - on observational phenomena are estimated by comparing the limiting cases that th...
Nuclear parton distributions and deviations from DGLAP at an Electron Ion Collider
QCD in nuclei PDFs electron ion collider

We explore the potential of an Electron Ion Collider to determine nuclear modifications of PDFs.
Nuclear effects in atomic transitions

2011/7/21
Atomic electrons are sensitive to the properties of the nucleus they are bound to, such as nuclear mass, charge distribution, spin, magnetization distribution, or even excited level scheme.
Leading twist nuclear shadowing phenomena in hard processes with nuclei
shadowing phenomena hard processes nuclei
font style='font-size:12px;'>
2011/7/21
We present and discuss the theory and phenomenology of the leading twist theory of nuclear shadowing which is based on the combination of the generalization of Gribov-Glauber theory, QCD factorization...
Photon-tagged heavy meson production in high energy nuclear collisions
Photon-tagged heavy meson high energy nuclear collisions
font style='font-size:12px;'>
2011/7/21
We study the photon-triggered light and heavy meson production in both p+p and A+A collisions. We find that a parton energy loss approach that successfully describes inclusive hadron attenuation in nu...

font style='font-size:12px;'>
2011/7/21
In this review we first outline the basics of transport theory and its recent generalization to off-shell transport. We then present in some detail the main ingredients of any transport method using i...
Quarkonium as a tool: cold nuclear matter effects
Quarkonium Shadowing Cold Nuclear Matter e ects

2011/7/21
We discuss the quarkonium production as a tool for the study of the Quark Gluon Plasma. In particular, we concentrate on the Cold Nuclear Matter effetcs.
Nuclear de-excitation line spectrum of Cassiopeia A
Astroparticle physics – cosmic rays – ISM: supernova remnants
font style='font-size:12px;'>
2011/10/13
The supernova remnant Cassiopeia A is a prime candidate for accelerating cosmic ray protons and ions. Gamma rays have been observed at GeV and TeV energies, which indicates hadronic interactions, but ...

2011/7/21
In this paper we study the effect of, well-known, higher order corrections to the allowed beta decay spectrum on the determination of anti-neutrino spectra resulting from the decays of fission fragmen...
Nuclear matter and chiral phase transition at large-$N_{c}$
Institute of theoretical Physics, Johann Wolfgang Goethe University
font style='font-size:12px;'>
2011/7/21
Two aspects of the QCD phase diagrams are studied in the limit of a large number of colors: at zero temperature and nonzero density the (non)existence of nuclear matter, and at zero density and nonzer...
Neutrino Quasielastic Scattering on Nuclear Targets: Parametrizing Transverse Enhancement (Meson Exchange Currents)

2011/7/21
We present a parametrization of the observed enhancement in the transverse electron quasielastic (QE) response function for nucleons bound in carbon as a function of the square of the four momentum tr...
The Time-Reversal- and Parity-Violating Nuclear Potential in Chiral Effective Theory

2011/7/20
We derive the parity- and time-reversal-violating nuclear interactions stemming from the QCD theta term and quark/gluon operators of effective dimension 6: quark electric dipole moments, quark and glu...
