Meson beam optimization for precision measurements of the leptonic CP violating phase in low energy nuSTORM facility

In the first hundred-thousandth of a second after the big bang, an equal amount of particles and antiparticles were created. They were also constantly annihilating each other resulting in radiation; hence, only radiation would have been left now. However, the observable universe—including galaxies, stars, etc.—and even ourselves are made of particles, whereas there is no antiparticle in the universe. We cannot explain how this happened. In this international scientific collaboration, we tackle this question at the fundamental level of particle physics. We believe that neutrinos may in fact be responsible for the nonsurvival of all the antimatter created in the big bang. We will try to understand the contribution of neutrinos in these areas by precisely measuring the parameters governing ν-oscillations, especially the leptonic CP-violating phase, using a long-baseline neutrino project supported by nuSTORM and monitored low-energy neutrino beam facilities.
