2011/7/21
Multijet cross sections at the LHC and Tevatron are sensitive to several distinct kinematic energy scales.
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...
Can transport peak explain the low-mass enhancement of dileptons at RHIC?
dileptons at RHIC
2011/7/20
We propose a novel relation between the low-mass enhancement of dielectrons observed at PHENIX and transport coefficients of QGP such as the charge diffusion constant $D$ and the relaxation time $\tau...
Nuclear dynamics at the balance energy of mass asymmetric colliding nuclei
heavy-ion collisions uantum molecular dynamics (QMD) model
2011/7/20
Using the quantum molecular dynamics model, we study the nuclear dynamics at the balance energy of mass asymmetric colliding nuclei by keeping the total mass of the system fixed as 40, 80, 160, and 24...

asymmetric colliding nuclei balance energy
2011/7/20
Using the quantum molecular dynamics model, we study the role of mass asymmetry of colliding nuclei on the fragmentation at the balance energy and on its mass dependence. The study is done by keeping ...
Impact parameter dependence of collective flow and its disappearance for different mass asymmetries
collective flow parameter dependence
2011/7/20
We study the role of impact parameter on the collective flow and its disappearance for different mass asymmetric reactions. The mass asymmetry is varied from 0 to 0.7 keeping the total mass of the sys...
Recent lattice QCD calculations have reported evidence for the existence of a bound state with strangeness -2 and baryon number 2 at quark masses somewhat higher than the physical values.
Uncertainties in nuclear transition matrix elements for neutrinoless $ββ$ decay II: the heavy Majorana neutrino mass mechanism
matrix elements neutrino mass mechanism
2011/7/20
Employing four different parametrization of the pairing plus multipolar type of effective two-body interaction and three different parametrizations of Jastrow-type of short range correlations, the unc...
Stability of fragments and study of participant-spectator matter at peak center-of-mass energy
center-of-mass energy participant-spectator matter
2011/7/20
We simulate the central reactions of nearly symmetric, and asymmetric systems, for the energies at which the maximum production of IMFs occurs (E$_{c.m.}^{peak}$).This study is carried out by using ha...
Novel charmonium-like structures in the $J/\psi\phi$ and $J/\psi\omega$ invariant mass spectra
Novel charmonium-like structures
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...
We present results from CDF and DØ on direct searches for high mass standard model (SM) Higgs boson (H) in p¯p collisions at the Fermilab Tevatron at √s = 1.96 TeV. Compared to previous Hi...

The energies of the excited states of the Nucleon, D and W are computed in lattice QCD, using
two light quarks and one strange quark on anisotropic lattices. The calculations are performed at three v...

2011/1/7
A correction to the nuclear functional is proposed in order to improve the density of states around the Fermi surface. The induced effect of this correction is to produce a surface-peaked effective ma...

With growing datasets collected by the CDF II experiment, studies of the spectroscopy of mesons
containing heavy quarks become more exciting. The CDF experiment has good capabilities in
both charm a...
