hadronn.

Brit.

/ˈhadrɒn/, U.S.

/ˈhædˌrɑn/

Origin: A borrowing from Greek, combined with an English element. Etymons: Greek ἁδρός , -on suffix¹.

Etymology: < ancient Greek ἁδρός thick, solid, large (see Hadrosaurus n.) + -on suffix¹. Apparently coined in English by the Russian physicist L. B. Okun (b. 1929). Compare Russian adron (1963 or earlier). With hadronic adj. at Derivatives compare Russian adronnyj (1963 or earlier).

Particle Physics.

Any strongly interacting subatomic particle. Cf. lepton n.² 2.Hadrons include baryons (nucleons and hyperons), each with three quarks, and mesons, each with two.

hadron1962

1962 L. B. Okun in Proc. Internat. Conf. High-Energy Physics 845/2 In this report I shall call strongly interacting particles hadrons, and the corresponding decays hadronic.

1966 New Scientist 26 May 500/1 The particles, so-called baryons and mesons, collectively called hadrons.

1968 Sci. Jrnl. Nov. 34/2 Weak decays of hadrons—which are nucleons (neutrons and protons) and their heavy partners.

1976 C. Holland Floating Worlds (1977) 134 I'll give you ten minutes to leave before I blow you to hadrons.

1987 D. H. Perkins Introd. High-Energy Physics (ed. 3) i. 17 W^±-exchange results in change of charge of the lepton and hadron taking part.

1991 Independent 16 Dec. 13/1 The new machine, known as the Large Hadron Collider (LHC), will collide elementary particles at such high energies as to create the conditions prevailing in the universe during the first millionth of a millionth of a second after the Big Bang.

2008 Canberra Times (Nexis) 18 Oct. 15 The hadrons and leptons, the atoms and molecules that fill the inside of our cranium are no different from the same particles in rocks or cabbage.

Compounds

hadron collider n. a particle accelerator in which hadrons are accelerated to high levels of kinetic energy and made to collide with one another; frequently attributive; cf. large hadron collider n. at large adj., adv., and n. Compounds 4.

ΚΠ

1979 Physical Rev. D. 20 2862/2 Quark searches could therefore develop as a major mission of the hadron colliders.

1994 Nuovo Cimento A. 107 2179 The highest hadron collider energies are clearly essential.

2006 F. Wilczek Fantastic Realities 390 This Higgs–gluon vertex..could be exploited for production of Higgs particles, at hadron colliders, through ‘gluon fusion’.

Derivatives

haˈdronic adj. of or relating to a hadron; involving hadrons.

1987 Physics Lett. B. 186 222 The measurement of the ratio of leptonic and hadronic decay widths.

2011 L. Randall Knocking Heaven's Door xiii. 231 Energy measurements are simply harder for strongly interacting particles, independent of segmentation, since the energy in hadronic showers fluctuates more.
