The extensions of the Standard Model based on the SU(3)C⊗SU(3)L⊗U(1)X gauge group are known as 331 models. Different properties such as the fermion assignment and the electric charges of the exotic spectrum, which define a particular 331 model, are fixed by a β parameter. In this work, we study the electric charge quantization in two versions of the 331 models, set by the conditions β=1/(33–√)...
Using a Monte Carlo method, the measurement by the double energy technique (2E) of the average prompt neutron multiplicity as a function of the mass of fragments from the thermal neutron-induced fission of 239Pu is simulated. The input data, associated with the masses of complementary primary fragments (A, A'), consist of the yield (Y), the average total kinetic energy ((TKE) ̅) and its...
La busqueda de una nueva Física, como se le llama a las diversas extensiones del Modelo Estandar (ME) de la física de partículas, nos motiva ha extender el grupo de simetría Electro-débil de $SU(2)_{L}\,\otimes\, U(1)_{Y}$ al grupo de gauge con simetría left-right $SU(2)_{L}\,\otimes\,SU(2)_{R}\,\otimes\, U(1)_{B-L}\otimes\mathcal{P}$, donde $\mathcal{P}$ representa una simetría discreta de...
The general objective of the LA-CoNGA-Physics project is to bring the digital transition closer to eight Latin American institutions of higher education in the Andean region (Colombia, Ecuador, Peru and Venezuela) with the support of local and European partners. Thus, our main objective is to offer in 2021 an educational program within the Latin American Alliance in Advanced Physics for...
We studied the response of the Beam II Test Detector to electron and positrons beams for energies in range of 2−8 GeV. The beams were under different parameters (electromagnetic cascade opening angle, electromagnetic cascade starting module and energy absorbed by the calorimeter). Our method has allowed the differentiation of electron from positron beams, unmistakably for energies in the range...
Como parte de un plan para medir la seccin transversal total y diferencial del meson charmoso D0, trabajamos con sus dos principales modos de decaimiento. La idea no es medir directamente la seccin transversal absoluta, sino medirlas con respecto a una sección transversal D0, ya medida en este experimento E791. Demostraremos el valor de la técnica de razones de ramificación mostrando datos...
