Chiral corrections to the vector and axial couplings of quarks and baryons
Vector the axial quark coupling lorentz covariance coupling control octet weight baryon matrix elements

2014/12/19
We calculate chiral corrections to the semileptonic vector and axial quark coupling constants using a manifestly Lorentz covariant chiral quark approach up to order O(p4) in the two- and three-flavor ...
Magnetic Moments of Negative-Parity Baryons from Lattice QCD
Negative-Parity Baryons Lattice QCD
font style='font-size:12px;'>
2011/1/7
We report preliminary results for the magnetic moments of negative-parity baryons extracted from mass shifts in the presence of static external magnetic fields. The calculations are done on $24^3\time...
Heavy Quark Spin Symmetry and Heavy Baryons: Electroweak Decays
Heavy Quark Spin Symmetry Heavy Baryons Electroweak Decays
font style='font-size:12px;'>
2011/1/7
Heavy quark spin symmetry is discussed in the context of single and doubly heavy baryons. A
special attention is paid to the constraints/simplifications that this symmetry imposes on the non-relativi...

Radiative decays of dynamically generated charmed baryons
Radiative decays of dynamically charmed baryons
font style='font-size:12px;'>
2011/1/10
In this work we study the radiative decay of dynamically generated JP = 12 − charm baryons into the ground state JP = 1 2 + baryons. Since different theoretical interpretations of these baryonic...

2011/1/7
We show that a purely s-wave interaction in three dimensions (3D) can induce higher partialwave
resonances in mixed dimensions. We develop two-body scattering theories in all three cases of
0D-3D, 1...

2010/3/16
The flavor asymmetry of the nucleon sea, i.e., the excess of $d\bar{d}$ quark-antiquark pairs over $u\bar{u}$ ones in the proton can be explained by several different models; therefore, it is a chal...

2009/11/24
The ``good" diquark is employed to study Λc+ baryons within a mass loaded flux tube model. The study indicates that all Λc+ baryons candidates in the 2008 review by the Particle Data Group (PDG) are w...
