Diagonal and transition magnetic moments of negative parity heavy baryons in QCD sum rules

Diagonal and transition magnetic moments of the negative parity, spin-1/2 heavy baryons are studied in framework of the light cone QCD sum rules. By constructing the sum rules for different Lorentz structures, the unwanted contributions coming from negative (positive) to positive (negative) parity transitions are removed. It is obtained that the magnetic moments of all baryons, except $\Lambda_b^0$, $\Sigma_c^+$ and $\Xi_c^{\prime +}$, are quite large. It is also found that the transition magnetic moments between neutral negative parity heavy $\Xi_Q^{\prime 0}$ and $\Xi_Q^0$ baryons are very small. Magnetic moments of the $\Sigma_Q \to \Lambda_Q$ and $\Xi_Q^{\prime \pm} \to \Xi_Q^\pm$ transitions are quite large and can be measured in further experiments.Comment: 31 pages, 4 figures, LaTeX formatted. arXiv admin note: substantial text overlap with arXiv:1504.00172, arXiv:1504.0818

VERSATILE CATALYTIC TRANSFER HYDROGENATIONS IN ORGANIC SYNTHESIS

Catalytic transfer hydrogenation reactions are extremely useful in organic synthesis. We have investigated numerous reactions with ammonium formate (and other hydrogen gas donor) and 10% Pd/C successfully without using hydrogen gas. The reactions are very fast and produced products with high yields. Reduction of unsaturated groups, hydrogenolysis, reductive bond cleavage, allylic deacetoxylation, and dehalogenation are conducted using this method. In some instances, useful selectivity of reactions is observed. Most of the reactions are investigated with β-lactams as the substrates
