i think i actually might do it |
Do it! If you need inspiration, look for Mike Koglin's set from 31st Dec 1999. A couple of minutes before midnight, the mixed in Carmina Burana and, a few seconds before the New Year, he turned the music down and played a typical British message ("On the third stroke, the time will be 12:00 am, precisely") and, after these 3 strokes, it was a riot. Naturally, you're not in Britain, and it's not NYE, but you could record a sound sample from a doco about the Collider (say when they'll turn it on) and then add a countdown or something. |

Does this make sense to anyone?
quote: | A hadron (pronounced /hɑːdɹɒn/, from Greek ἁδρός, hadros, thick), in particle physics, is any strongly interacting composite subatomic particle. All hadrons are composed of quarks. Hadrons are divided into two classes, according to their baryon number:
* Baryons are all hadrons with a baryon number of 1. Baryons are fermions.
* Triquarks are baryons made of three quarks, such as the proton and the neutron.
* Pentaquarks are exotic baryons made of four quarks and one antiquark. While there is some evidence for their existence, data are controversial and the existence of pentaquarks is neither firmly established nor generally accepted.
* Generally speaking, baryons must have three more quarks than antiquarks. A baryon made of five quarks and two antiquarks would be a heptaquark, one made of six quarks and three antiquarks would be a nonaquark, and so on. It is not known if these particles can even exist.
* Mesons are all hadrons with a baryon number of 0. Mesons are bosons
* Diquarks are mesons made of one quark and one antiquark, such as the rho meson and the kaon.
* Tetraquarks are mesons made of two quarks and two antiquarks. While there is some evidence for their existence, data are controversial and the existence of tetraquarks is neither firmly established nor generally accepted.
* Generally speaking, mesons must have an equal number of quarks and antiquarks. A meson made of three quarks and three antiquarks would be a hexaquark, one made of four quarks and four antiquarks would be a octaquark, and so on. It is not known if these particles can even exist.
* It should be noted that while mesons are composite bosons, they are not made of bosons. Rather they are bosons made of quarks, which are fermions.
Like all subatomic particles, hadrons have quantum numbers corresponding to the representations of the Poincaré group: JPC(m), where J is the spin, P, the parity, C, the C parity, and m, the mass. In addition they may carry flavour quantum numbers such as isospin (or G parity), strangeness etc. Moreover,
* Baryons always carry an additive conserved quantum number called baryon number (B). B=1 for nucleons (the proton and the neutron), which are part of the atomic nucleus.
* Mesons have B=0.
Most hadrons can be classified by the quark model which posits that all the quantum numbers are derived from those of the valence quarks (the quarks which form the hadron). For instance, since each quark has B=1/3, each baryon, composed of three quarks, has B=1.
Excited baryon or meson states are known as resonances. Each ground state hadron may have many excited states, and hundreds have been observed in particle experiments. Resonances decay extremely quickly (within about 10^−24 s) via strong interactions.
Mesons which lie outside the quark model classification are called exotic mesons. These include glueballs, hybrid mesons and tetraquarks. The only baryons which lie outside the quark model at present are the pentaquarks, but evidence for their existence is unclear as of 2006.
All hadrons are single particle excitations of the basic theory of strong interactions, called quantum chromodynamics. Due to a property called confinement that this theory enjoys at energies below the QCD scale, these excitations are not quarks and gluons, which are the basic fields, but the hadrons which are composite, and carry no color charge.
In other phases of QCD matter the hadrons may disappear. For example, at very high temperature and high pressure, unless there are sufficiently many flavors of quarks, QCD predicts that quarks and gluons will interact weakly and in particular no longer be confined. This property, which is known as asymptotic freedom, has been experimentally confirmed at the energy scales between a GeV and a TeV. |
