Strangeness is an excited state of matter and its decay is governed by CKM mixing. The terms strange and strangeness predate the discovery of the quark, and were adopted after its discovery in order to preserve the continuity of the phrase: strangeness of particles as −1 and anti-particles as +1, per the original definition.
Strangeness (Italian: La stranezza) is a 2022 Italian comedy-drama film directed by Roberto Andò. [ 1 ] [ 2 ] The film won four David di Donatello awards, for best original screenplay, best producer, best production designer and best costumes. [ 3 ]

This is a list of television programs currently broadcast (in first-run or reruns), scheduled to be broadcast, or formerly broadcast on Bang Bang, an Albanian television channel by DigitAlb that airs a mix of animated television series, animated and live-action films as well as live-action Albanian originals produced by DigitAlb.
This gives new eigenvectors, which we can call K 1 which is the difference of the two states of opposite strangeness, and K 2, which is the sum. The two are eigenstates of CP with opposite eigenvalues; K 1 has CP = +1, and K 2 has CP = −1 Since the two-pion final state also has CP = +1, only the K 1 can decay this way.
Neither the strong interaction nor electromagnetism permit flavour changing, so this can only proceed by weak decay; without weak decay, quark properties such as strangeness and charm (associated with the strange quark and charm quark, respectively) would also be conserved across all interactions. All mesons are unstable because of weak decay.
A strange particle is an elementary particle with a strangeness quantum number different from zero. Strange particles are members of a large family of elementary particles carrying the quantum number of strangeness, including several cases where the quantum number is hidden in a strange/anti-strange pair, for example in the ϕ meson.
While studying these decays, Murray Gell-Mann (in 1953) [4] [5] and Kazuhiko Nishijima (in 1955) [6] developed the concept of strangeness (which Nishijima called eta-charge, after the eta meson (η)) to explain the "strangeness" of the longer-lived particles. The Gell-Mann–Nishijima formula is the result of these efforts to understand strange ...
The charm quark, charmed quark, or c quark is an elementary particle found in composite subatomic particles called hadrons such as the J/psi meson and the charmed baryons created in particle accelerator collisions.
