Symmetry limit properties of decay amplitudes with mirror matter admixtures

Gabriel Sanchez-Colon, Augusto Garcia

We extend our previous analysis on the symmetry limit properties of non-leptonic and weak radiative decay amplitudes of hyperons in a scheme of mirror matter admixtures in physical…

An estimate of a lower bound on the masses of mirror baryons

A. Garcia, R. Huerta, G. Sanchez-Colon

We consider the most favorable conditions to indirectly observe the mixing of ordinary and mirror hadrons in non-leptonic and weak radiative decays of hyperons. This allows us to s…

Masses, Magnetic Moments, and Semileptonic Decays of Spin 1/2 Baryons with Sea Contribution

V. Gupta, P. Ritto, G. Sanchez-Colon

The spin 1/2 baryons are pictured as a composite system made out of a "core" of three valence quarks (as in the simple quark model) surrounded by a "sea" (of gluon and p…

Quark Mixing Possibilities in Extensions of the Standard Model and the Electromagnetic Current

A. Garcia, R. Huerta, G. Sanchez-Colon

The existence of new quarks may lead to their mixing with ordinary quarks. We are particularly interested in studying the consequences such mixings could have upon the electromagne…

Semileptonic decays, magnetic moments and spin distributions of spin-1/2 baryons with sea contribution

V. Gupta, R. Huerta, G. Sanchez-Colon

Spin-1/2 baryons are considered as a composite system made out of a "core" of three quarks surrounded by a "sea" (of gluons and -pairs) which is specified by its total qu…
