Spontaneous CP Violation Jarlskog Invariant in SM⊗S3
Journal Title: Journal of Nuclear Physics, Material Sciences, Radiation and Applications - Year 2018, Vol 6, Issue 1
Abstract
In our days, CP (Charge Parity) violation in the Standard Model of fundamental interactions still remains as an open problem. It is well known that explicit CP violation may be included by imposing complex Yukawa couplings in the Yukawa sector or complex Higgs couplings in extended Higgs sectors with more than one Higgs field. It is desirable to have a fundamental CP violation theory, in that sense, we analyse the different scenarios for Spontaneous CP violation in an extended Higgs model with three Higgs fields and a discrete flavour permutational symmetry S3. Spontaneous CP violation effects contribute to the Higgs mass matrix, as well as, up and down quark mass matrices. This complex quark mass matrices allow us to study the conditions for a non-vanishing Jarlskog invariant J which provides a necessary and sufficient contribution for a spontaneous CPV coming from SM ⊗ S3

Analysis and characterization of neutron scattering of a Linear Accelerator (LINAC) on medical applications.
In several theoretical and experimental studies, the topic of the undesirable generation of photoneutrons in rooms where a linear accelerator (LINAC) operates has been discussed. When energies above 10 MeV are used to pr...
Enhancement in the Photoluminescence Properties of SiO2:Ge Embedded in a Polymeric Matrix
Polymer films of styrene butadiene copolymer (SBC) mixed with SiO2:Ge powder were successfully obtained by the drop casting method. The SBC concentration (in chloroform solution) was 10%w/v and the SiO2:Ge powder was mix...
Shape Transition to a Rare Shape Phase of Prolate Non-collective in A=100 Isobars
A theoretical investigation on the shape transitions with neutron number, temperature and spin for A = 100 isobars of Z = 42 to 50 is presented. A variety of shape transitions are observed while moving from neutron rich...
Development of Silicon Sensor Characterization System for Future High Energy Physics Experiments
