Characterization of the gaseous companion κ Andromedae b: New Keck and LBTI high-contrast observations
M. Bonnefoy, T. Currie, G. -D. Marleau +64
We previously reported the direct detection of a low mass companion at a projected separation of 55+-2 AU around the B9 type star κ Andromedae. The properties of the system (mass r…
Polarized light-antiquark distributions in a meson-cloud model
S. Kumano, M. Miyama
Flavor asymmetry is investigated in polarized light-antiquark distributions by a meson-cloud model. In particular, rho meson contributions to Delta u-bar - Delta d-bar are calculat…
Parton distribution functions in nuclei
M. Hirai, S. Kumano, M. Miyama
Optimum nuclear parton distributions are determined by an analysis of muon and electron deep inelastic scattering data. Assuming simple A dependence and polynomial functions of x a…
Parametrization of nuclear parton distributions
M. Hirai, S. Kumano, M. Miyama
Optimum nuclear parton distributions are obtained by analyzing available experimental data on electron and muon deep inelastic scattering (DIS). The distributions are given at Q^2=…
Determination of nuclear parton distributions
M. Hirai, S. Kumano, M. Miyama
Parametrization of nuclear parton distributions is investigated in the leading order of alpha_s. The parton distributions are provided at Q^2=1 GeV^2 with a number of parameters, w…
Determination of polarized parton distribution functions
M. Hirai, H. Kobayashi, M. Miyama
We study parametrization of polarized parton distribution functions in the α_s leading order (LO) and in the next-to-leading order (NLO). From χ^2 fitting to the experimental data…
