Perfect transmission of 3D massive Kane fermions in HgCdTe Veselago lenses
Y Betancur-Ocampo, V Gupta
The transmission properties of three-dimensional (3D) massive Kane fermions in HgCdTe (MCT) heterojunctions have been studied using the simplified Kane-Melé model. Based on our the…
Decay coupling constants sum rules for dibaryon octet into two baryon octets with first order SU(3) symmetry breaking
E. N. Polanco-Euán, V. Gupta, G. Sánchez-Colón +1
The SU(3) octet states with baryon number B = 2, hexaquark dibaryons, are considered. Decay coupling constants sum rules for dibaryon octet into two ordinary baryon octets with ?$λ…
Dibaryon decay sum rules and other multiquark states
E. N. Polanco-Euán, V. Gupta, G. Sánchez-Colón +1
The decays of the antisymmetric dibaryon octet into two baryon octets are considered. Sum rules for these decays in first order broken SU(3) are given. An SU(4) extension…
Transmission properties of the one-dimensional array of delta potentials
G. Cordourier-Maruri, R. de Coss, V. Gupta
The problem of one-dimensional quantum wire along which a moving particle interacts with a linear array of N delta-function potentials is studied. Using a quantum waveguide approac…
Recursive parametrization of Quark flavour mixing matrices
S. Chaturvedi, V. Gupta, G. Sánchez-Colón +1
We examine quark flavour mixing matrices for three and four generations using the recursive parametrization of and matrices developed by some of us in Refs.[2] and […
A new approach to the parametrization of the Cabibbo-Kobayashi-Maskawa matrix
V. Gupta
The CKM-matrix V is written as a linear combination of the unit matrix I and a matrix U which causes intergenerational-mixing. It is shown that such a V results from a class of qua…
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…
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…
Scalar Sea Contributions to Spin 1/2 Baryon Structure and Magnetic Moments
V. Gupta, R. Huerta, G. Sanchez-Colon
We treat the baryon as a composite system made out of a "core" of three quarks (as in the standard quark model) surrounded by a "sea" (of gluons and -pairs) which is spec…
Sea Contributions to Spin 1/2 Baryon Structure, Magnetic Moments, and Spin Distribution
V. Gupta, R. Huerta, G. Sanchez-Colon
We treat the baryon as a composite system made out of a \lq\lq core" of three quarks (as in the standard quark model) surrounded by a \lq\lq sea" (of gluons and -pairs) w…
Sea Contributions and Nucleon Structure
X. Song, V. Gupta
We suggest a general formalism to treat a baryon as a composite system of three quarks and a `sea'. In this formalism, the sea is a cluster which can consists of gluons and quark-a…
