Isospin breaking and chiral symmetry restoration

We analyze quark condensates and chiral (scalar) susceptibilities including isospin-breaking effects at finite temperature T. These include mu md contributions as well as electromagnetic (e 0) corrections, both treated in a consistent chiral Lagrangian framework to leading order in SUð2Þ and SUð3Þ chiral perturbation theory, so that our predictions are model-independent. The chiral restoration ...

Pairing and alpha-like quartet condensation in N=Z nuclei

We discuss the treatment of isovector pairing by an alpha-like quartet condensate which conserves exactly the particle number, the spin and the isospin. The results show that the quartet condensate describes accurately the isovector pairing correlations in the ground state of systems with an equal number of protons and neutrons. One of the most debated topic in nuclear physics is the competitio...

Extraction of Vud from superallowed Fermi b decay by the Wilkinson techniques

The up–down element Vud of the Cabibbo–Kobayashi–Maskawa (CKM) quark mixing matrix is derived from superallowed Fermi b decays between isospin T 1⁄4 1 states using the semi-empirical techniques pioneered by D.H. Wilkinson. Rather than relying directly on the absolute magnitude of theoretical nuclear structure calculations to correct each decay for isospin symmetry breaking effects, these method...

Isobaric multiplet mass equation for A = 7 and 8

Typically cubic and quartic terms (dT 3 Z + eT 4 Z ) are added to the IMME to provide a measure of any deviation from the quadratic form associated with isospin symmetry. In general, the quadratic form (d = 0 and e = 0) provides a good description of isospin quartets and quintets for A < 40 where the appropriate experimental masses are known [1]. The success of IMME has lead people to use it to...

ELUCIDATION OF pK VALUES FOR ACTIVE SITE OF HORSERADISH PEROXIDASE AND BINDING STUDY OF INTERACTION WITH N-PHENYL BENZHYDROXAMIC ACID USING A SPECIAL DIFFERENCE SPECTROPHOTOMETRIC TECHNIQUE

The binding behavior of a competitive inhibitor, N-phenylbenzhydroxamic acid (BHA) against horseradish peroxidase (HRP) was studied in order to understand and predict the interaction mechanism of hydrogen donors with the enzyme. The dissociation constants of the complexes of HRP-BHA, HRP-donor and HRP-BHA-azide were estimated at specified conditions by difference spectroscopy. The binding s...
