Brinjevec is a candidate for the classification as a specialty on the list of world-famous drinks. "Kraški brinjevec" is made of juniper berries from the species "Juniperus communis". "Juniperus communis" is a barbed evergreen shrub or low tree that grows in a dry karst terrain. It is a monosex plant and only female plants grow berries. Juniper berries ripen only every two or even three years, so the same bush often carries mature and immature berries. Mature berries are fleshy, dark blue, refreshing fruity smell with a bit sweet and bitter taste. Berries are gathered in October and November with a
Flavour (particle physics) description of the flavour symmetry is described by a chiral group . If all quarks had non-zero but equal masses, then this chiral symmetry is broken to the "vector symmetry" of the "diagonal flavour group" , which applies the same transformation to both helicities of the quarks. This reduction of symmetry is a form of "explicit symmetry breaking". The amount of explicit symmetry breaking is controlled by the current quark masses in QCD. Even if quarks are massless, chiral flavour symmetry can be spontaneously broken if the vacuum of the theory contains a chiral condensate (as it does in low-energy
