The |∆I| = 1/2 rule in non-leptonic decays of hyperons can be naturally understood by postulating a priori mixed physical hadrons, along with the isospin invariance of the responsible transition operator. It is shown that this operator can be identified with the strong interaction Yukawa hamiltonian. The experimental amplitudes are well reproduced.
A priori mixed hadrons, hyperon non-leptonic decays, and the |∆I| = 1/2 rule Abstract. The |∆I| = 1/2 rule in non-leptonic decays of hyperons can be naturally understood by postulating a priori mixed physical hadrons, along with the isospin invariance of the responsible transition operator. It is shown that this operator can be identified with the strong… (More)
This paper describes a simple way to control, in a sensorless way, a Brushless DC (BLDC) motor for electric vehicle applications. To control this machine it is generally required to count with a position sensor because the inverter phases, acting at any time, must be commuted depending on the rotor position. Encoders and resolvers have been used for sensing… (More)
A priori mixed hadrons, weak radiative and non-leptonic decays of hyperons Abstract A priori mixings of eigenstates in physical states are quantum mechanical effects well known in several realms of physics. The possibility that such effects are also present in particle physics, in the form of flavor and parity mixings, is studied. Applications to weak… (More)
Strong-flavor and parity a priori mixing in hadrons are shown to describe well the experimental evidence on weak radiative decays of hyperons. An independent determination of the a priori mixing angles is performed. The values obtained for them are seen to have a universality–like property, when compared to their values in non-leptonic decays of hyperons.
INTRODUCTION Dexterity is described as coordinated hand and finger movement for precision tasks. It is essential for day-to-day activities like computer use, writing or buttoning a shirt. Integrity of brain motor networks is crucial to properly execute these fine hand tasks. When these networks are damaged, interventions to enhance recovery are frequently… (More)
