Concerning nonadiabatic processes, two different proofs of the Landau-Zener (LZ) formula are studied, and an analogue to the formula is provided for a specific 3 × 3 case. Lastly, an approximate bound to nonstandard interaction (NSI) coefficients of solar neutrino oscillations is derived from the LZ formula.5 p.application/pdfengcc-by-nc-nd (c) Piquer, 2023http://creativecommons.org/licenses/by-nc-nd/3.0/es/Teorema adiabàticFórmula de Landau-ZenerTreballs de fi de grauAdiabatic theoremLandau–Zener formulaBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
