- ECM - PF - 04 - 05 M ( B ∗ c ) − M ( B c ) Splitting from Nonrelativistic Renormalization Group

چکیده
We compute the hyperfine splitting in a heavy quarkonium composed of different flavors in next-to-leading logarithmic approximation using the nonrelativistic renormalization group. We predict the mass difference of the vector and pseudoscalar charmbottom mesons to be M(B c )−M(Bc) = 48± 15 (th) +14 −11 (δαs) MeV. PACS numbers: 12.38.Bx, 14.65.Fy, 14.65.Ha

متن کاملEffects of stock density on texture-colour quality and chemical composition of rainbow trout (Oncorhynchus mykiss)
This study describes the effects of different stocking densities on texture/colour characteristics, protein content /amino acid and lipid content/fatty acid composition of rainbow trout fillet. Stocking density was selected 5 (Group A), 15 (Group B), 25 (Group C) kg fish m−3. Tukey’s Multiple Comparison Test showed insignificant differences between measured size/weight measurement and condition f...

متن کاملThe effects of refining steps on Kilka (Clupeonella delicatula) fish oil quality
Kilka fish are known as the main industrial and pelagic species of Iran that are captured abundantly in the southern Caspian Sea. This study was conducted to survey the effectiveness of refinement steps on Kilka (Clupeonella delicatula) crude oil quality and fatty acid profiles. Neutralization, bleaching, winterization and deodorization were performed on crude oil with deodorization done under ...
