Flavor eigenstates are specific quantum states of particles, like neutrinos or quarks, that correspond to distinct types of interactions, such as weak interactions. These states can transform into one another through a process called flavor oscillation, which is a fundamental aspect of particle physics and contributes to the understanding of phenomena like neutrino oscillations and CP violation.

Neutrinos are nearly massless, electrically neutral subatomic particles that interact only via the weak nuclear force and gravity, making them incredibly difficult to detect. They are produced in vast quantities by nuclear reactions in stars, including our sun, and play a critical role in understanding fundamental processes in particle physics and cosmology.

Quarks are elementary particles and fundamental constituents of matter, combining to form protons and neutrons within atomic nuclei. They interact through the strong force, mediated by gluons, and come in six 'flavors': up, down, charm, strange, top, and bottom, each possessing unique properties such as charge and mass.

Particle physics is the branch of physics that studies the fundamental constituents of matter and the forces that govern their interactions. By exploring subatomic particles like quarks, leptons, and gauge bosons, it seeks to understand the underlying principles of the universe, often through high-energy experiments like those conducted in particle accelerators.

Neutrino oscillations are a quantum phenomenon where neutrinos change between different 'flavors' (electron, muon, and tau) as they travel through space, implying that they have mass. This discovery challenges the Standard Model of particle physics, which originally considered neutrinos to be massless.

CP violation refers to the phenomenon where the laws of physics change when particles are replaced with their antiparticles (C symmetry) and their spatial coordinates are inverted (P symmetry). This violation is crucial in explaining the matter-antimatter asymmetry in the universe, as it allows for processes that favor matter over antimatter.
