[ 1 ] - مطالعه انتشار همدوس لپتون‌های باردار ناشی از واپاشی پایون و W بوزون در مکانیک بوهمی
Although charged leptons, contrary to neutrinos, cannot oscillate, exploring whether a coherent superposition of charged lepton states can change to others during the propagation is an important problem in the neutrino oscillation theory. In this paper, we consider electrons and muons coming from the pions and W decays and study their propagation in relativistic Bohmian quantum mechanics. We f...
[ 2 ] - استتار گشتاور دوقطبی الکتریکی الکترون در اتم با استفاده از نمایش فولدی- وادهازن
The existent of the intrinsic electric dipole moments (EDM) lead to CP violation in a physical system. In the non-relativistic and point like limits, the effects of them in atoms are canceled which is well-known as Schiff screening effects. It is why that the energy shift due to the EDM is proportional to the expectation value of which vanishes in non-relativistic limit. In this paper, using F...
[ 3 ] - پراکندگی نوترینوی میونی از روی الکترون قطبیده به الکترون و نوترینو در فضا- زمان ناجابه‌جایی
For neutrino scattering from polarized electron, the weak interaction term in the cross section is significantly suppressed by the polarized term. The magnetic moment term does not receive any correction from the electron polarization. Hence, the study of the magnetic moment of neutrinos through scattering from the polarized electron leads to a stronger bound on the neutrino magnetic moment com...
