Abstract We conduct a model-independent analysis of the distinct signatures of various generic new physics possibilities in the decay $$B \rightarrow K \, \nu \, \overline{\nu }$$ B → K ν ν ¯ by analyzing the branching ratio as well as the missi

Practical Dirac Majorana confusion theorem: issues and applicability

Autor: C. S. Kim

Publikováno v: European Physical Journal C: Particles and Fields, Vol 83, Iss 10, Pp 1-13 (2023)

Abstract We inspect the model-independent study of practical Dirac Majorana confusion theorem (pDMCT) – a wide spread belief that the difference between Dirac and Majorana neutrinos via any kinematical observable would be practically impossible to

This study aimed to draw up a risk map of predicting the potential failure zone and impulse that may occur due to the fall of trees in the palace. The main findings of the study are as follows. First, a formula for calculating a failure zone and impu

Probing the non-standard neutrino interactions using quantum statistics

Autor: C. S. Kim, Janusz Rosiek, Dibyakrupa Sahoo

Publikováno v: European Physical Journal C: Particles and Fields, Vol 83, Iss 3, Pp 1-17 (2023)

Abstract Using the well established principles of Lorentz invariance, CP and CPT symmetry, and quantum statistics we do a model-independent study of effects of possible non-standard couplings of (Dirac and Majorana) neutrinos. The study is sensitive

CP violation in the rare Higgs decays via exchange of on-shell almost degenerate Majorana neutrinos, H → v k N j → v k ℓ − U D ¯ $$ H\to {v}_k{N}_j\to {v}_k{\mathrm{\ell}}^{-}U\overline{D} $$ and H → v k N j → v k ℓ + U ¯ D $$ H\to {v}_k{N}_j\to {v}_k{\mathrm{\ell}}^{+}\overline{U}D $$

Abstract We investigate rare decays of Higgs via exchange of two almost degenerate heavy on-shell Majorana neutrinos N j (j = 1, 2): Γ ± = Γ(h → ν k N j → ν k ℓ ± π ∓), and into the open quark channels Γ ± = Γ(h → ν k N j → ν
