carrier particle for strong force
1Force carrier — This article is about force mediating particles in general. For the specific particles that mediate the electromagnetic, strong, and weak interactions, see gauge boson. In particle physics, quantum field theories such as the Standard Model… …
2Massless particle — In particle physics, a massless particle is a particle whose invariant mass is zero. Currently, the only known massless particles are gauge bosons: the photon (carrier of electromagnetism) and the gluon (carrier of the strong force). However,… …
3subatomic particle — or elementary particle Any of various self contained units of matter or energy. Discovery of the electron in 1897 and of the atomic nucleus in 1911 established that the atom is actually a composite of a cloud of electrons surrounding a tiny but… …
4weak force — Physics. a force between elementary particles that causes certain processes that take place with low probability, as radioactive beta decay and collisions between neutrinos and other particles. Also called weak interaction force. Cf. weak… …
5Exchange force — In particle physics, an exchange force is a force produced by the exchange of force carrier particles, such as the electromagnetic force produced by the exchange of photons between electrons and the strong force produced by the exchange of gluons …
6W particle — Physics. either of two types of charged intermediate vector bosons, one having a positive charge and the other a negative charge. Symbols: W+, W [1970 75; appar. for weak] * * * Electrically charged subatomic particle that transmits the weak… …
7M-theory — For a generally accessible and less technical introduction to the topic, see Introduction to M theory. String theory …
8Nobel Prizes — ▪ 2009 Introduction Prize for Peace The 2008 Nobel Prize for Peace was awarded to Martti Ahtisaari, former president (1994–2000) of Finland, for his work over more than 30 years in settling international disputes, many involving ethnic,… …
9Meson — Mesons Mesons of spin 0 form a nonet Composition Composite Quarks and antiquarks Statistics Bosonic …
10Mathematics and Physical Sciences — ▪ 2003 Introduction Mathematics Mathematics in 2002 was marked by two discoveries in number theory. The first may have practical implications; the second satisfied a 150 year old curiosity. Computer scientist Manindra Agrawal of the… …
