Strangeness

Index Strangeness

In particle physics, strangeness ("S") is a property of particles, expressed as a quantum number, for describing decay of particles in strong and electromagnetic interactions which occur in a short period of time. [1]

Abraham Pais

Abraham Pais (May 19, 1918 – July 28, 2000) was a Dutch-born American physicist and science historian.

Bottomness

In physics, bottomness (symbol B&prime) or beauty is a flavour quantum number reflecting the difference between the number of bottom antiquarks (n) and the number of bottom quarks (n) that are present in a particle: Bottom quarks have (by convention) a bottomness of −1 while bottom antiquarks have a bottomness of +1.

Charm (quantum number)

Charm (symbol C) is a flavour quantum number representing the difference between the number of charm quarks and charm antiquarks that are present in a particle: By convention, the sign of flavour quantum numbers agree with the sign of the electric charge carried by the quark of corresponding flavour.

Cross section (physics)

When two particles interact, their mutual cross section is the area transverse to their relative motion within which they must meet in order to scatter from each other.

Kaon

In particle physics, a kaon, also called a K meson and denoted,The positively charged kaon used to be called τ+ and θ+, as it was supposed to be two different particles until the 1960s.

Murray Gell-Mann

Murray Gell-Mann (born September 15, 1929) is an American physicist who received the 1969 Nobel Prize in physics for his work on the theory of elementary particles.

Particle

In the physical sciences, a particle (or corpuscule in older texts) is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass.

Particle decay

Particle decay is the spontaneous process of one unstable subatomic particle transforming into multiple other particles.

Particle physics

Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter and radiation.

Physical property

A physical property is any property that is measurable, whose value describes a state of a physical system.

Quantum number

Quantum numbers describe values of conserved quantities in the dynamics of a quantum system.

Strange quark

The strange quark or s quark (from its symbol, s) is the third lightest of all quarks, a type of elementary particle.

Strangeness production

Strangeness production is a signature and a diagnostic tool of quark–gluon plasma (or QGP) formation and properties.

Strong interaction

In particle physics, the strong interaction is the mechanism responsible for the strong nuclear force (also called the strong force or nuclear strong force), and is one of the four known fundamental interactions, with the others being electromagnetism, the weak interaction, and gravitation.

Time

Time is the indefinite continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future.

Topness

Topness (also called truth), a flavour quantum number, represents the difference between the number of top quarks (t) and number of top antiquarks that are present in a particle: By convention, top quarks have a topness of +1 and top antiquarks have a topness of −1.The term "topness" is rarely used; most physicists simply refer to "the number of top quarks" and "the number of top antiquarks".

Weak interaction

In particle physics, the weak interaction (the weak force or weak nuclear force) is the mechanism of interaction between sub-atomic particles that causes radioactive decay and thus plays an essential role in nuclear fission.
