Chiral perturbation theory for φ → ϱγγ and φ → ωγγ

φ φ φ φ φ φ k From Max - SAT to Min - UNSAT : Insights and Applications

This report describes a strong connection between maximum satisfiability and minimally-unsatisfiable subfor-mulas of any constraint system, as well as techniques for exploiting it. Focusing on CNF formulas, we explore this relationship and present novel algorithms for extracting minimally-unsatisfiable subformulas, including one that finds all such subformulas. We present experimental results s...

Φ-measure and Disoriented chiral condensates

Fluctuations in the ratio of neutral to charged pions arising due to formation of disoriented chiral condensates (DCC) are discussed using the Φ-measure. The properties of the measure for various cases of DCC and non-DCC are discussed. The effect of detector efficiencies and other experimental factors are presented. Application of the Φ-measure to simulated data, within the context of a simple ...

We show how the nearly bi-maximal mixing scenario comes out naturally from gauged SO(3) F flavor symmetry via spontaneous symmetry breaking. An interesting relation between the neutrino mass-squared differences and the mixing angle, i.e., ∆m 2 µe /∆m 2 τ µ ≃ 2|U e3 | 2 is obtained. The smallness of the ratio (or |U e3 |) can also naturally be understood from an approximate permutation symmetry....

The Φ → Π + Π − and Φ Radiative Decays within a Chiral Unitary Approach

Chiral Loop and Lσm Predictions for Φ → Π

A prediction for the contributions of chiral loops and the LσM model to the radiative φ → π 0 ηγ decay mode is presented. The LσM is used as an appropriate framework for describing the pole effects of the a 0 (980) scalar resonance. As a result, a better agreement with present available data is achieved for the higher part of the π 0 η invariant mass spectrum. For the branching ratio, a value o...
