Description
We discuss the effect of environmental decoherence on matter-effective neutrino
oscillation probabilities. Decoherence is a phenomenon observed in systems in-
teracting with the environment. We treat the neutrinos as an open quantum
system and by using the Lindblad Master equation we study the evolution of
neutrino states. The matter effect is incorporated for neutrinos passing through
matter with the help of the Cayley-Hamilton formalism.
In this work, we have developed a general algorithm that attempts to solve
the Lindblad Master Equation to compute the neutrino oscillation probabilities
in presence of environmental decoherence. We extensively validate the algorithm
and explore how environmentally induced decoherence can potentially affect the
oscillation probabilities, particularly in the long-baseline sector.
