Strange Quark Mass and $1^{++}$ Nonet Singlet-Octet Mixing Angle
Strange Quark Mass $1^{++}$ Nonet Singlet-Octet Mixing Angle
2011/1/7
We compute the strange quark mass from the analysis of the $f_1(1420)-f_1(1285)$ mass difference QCD sum rule, where the operator-product-expansion series is up to dimension six and to ${\cal O}(\alph...
Sea quark contents of octet baryons
balance model meson cloud model chiral quark model flavor asymmetry
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...
Dynamically generated resonances from the vector octet-baryon decuplet interaction and their radiative decays into γ-baryon decuplet
dynamically generated resonances chiral dynamics hidden gauge formalism for vector meson interaction
2009/11/24
The dynamically generated resonances from vector meson-baryon decuplet are studied using Lagrangians of the hidden gauge theory for vector interactions. One shows that some of the generated states can...
