Ouzo after the Greek city of Mystras in the Peloponnese is a version of ouzo made in Rome that closely resembles Greek and Cypriot ouzo. Ouzo Ouzo (, ) is a dry anise-flavoured aperitif that is widely consumed in Greece, Cyprus, Lebanon and Israel. Its taste is similar to other anise liquors like "rakı", pastis and sambuca. Ouzo has its roots in "tsipouro", which is said to have been the work of a group of 14th-century monks on Mount Athos. One version of it was flavoured with anise. This version eventually came to be called ouzo. Modern ouzo distillation largely took
Flavour (particle physics) a decay involving a bottom quark or antiquark . Since first-order processes are more common than second-order processes (involving two quark decays), this can be used as an approximate "selection rule" for weak decays. A special mixture of quark flavours is an eigenstate of the weak interaction part of the Hamiltonian, so will interact in a particularly simple way with the W bosons. (Charged weak interactions violate flavor). On the other hand, a fermion of a fixed mass (an eigenstate of the kinetic and strong interaction parts of the Hamiltonian) is an eigenstate of flavour. The transformation from the former
