Spinor Operator Giving Both Angular Momentum and Parity
T. Matsuki, K. Mawatari, T. Morii +1
In heavy quark effective theory, heavy mesons which contain a heavy quark (or antiquark) are classified by , i.e., the total angular momentum and the parity $pi_l…
Diffractive Lambda_c^+ Productions in Polarized pp Reactions and Polarized Gluon Distribution
N. I. Kochelev, T. Morii, S. Oyama
To test the model of the polarized gluon distribution in the proton, we propose a new process, diffractive productions in polarized reactions, which will…
Polarized light flavor sea-quark asymmetry in polarized semi-inclusive processes
T. Morii, T. Yamanishi
We propose new formulas for extracting a difference of the polarized light sea-quark density, , from polarized deep-inelastic semi-inclusive data. We have es…
A New Parametrization of Polarized Parton Distribution Functions
T. Morii
Requiring the positivity and counting rule, we propose a new parametrization of the polarized parton distribution which reproduce the data well. We found that the NLO analysis is a…
Spectroscopy and Decays of Heavy Mesons
Takayuki Matsuki, Toshiyuki Morii
Assuming Coulomb-like as well as confining scalar potential, we have solved Shrödinger equation perturbatively in with a heavy quark mass . The lowest order equation i…
The Spin Structure of Nucleons and Deep Inelastic Scatterings
Toshiyuki Morii
Based on a simple model which is compatible with the idea of the static quark model and the parton model, the polarized structure functions of proton and deuteron, two-spin asymmet…
