Hadron

Hadron

In particle physics, a headron  is a composite particle made of two or more quarks, one Equally similar to the molecules by strong force. Organized together by electromagnetic force. Most mass of ordinary matter comes from two headsrons, protons and neutrons.

Headron is classified into two families: Baron is composed of an odd number of quarks - usually three quarks - and mesons are made up of the same number of quarks - usually a quark and an antacarc. Examples of protons and neutron berries are; Lion is an example of a Mason. "Alien" Hadron have also been discovered in recent years which has more than three Valence Quarks, A tetraquark state (a foreign mason), whose name is Z (4430) - was discovered in 2007 by Belle's collaboration and was ratified in 2014 as a resonance by LHCb cooperation. Two pentaquark states (foreign baryons), named P +

c (4380) and P +

C (4450), was searched by LHCB in 2015. There are many more foreign headphones, and other color-singlet quark combinations are also present.

Almost all "free" headphones and antihurdon (meaning, in isolation and not bound within an atomic nucleus) are considered unstable and eventually decay in other particles (breaks down). The only known exception is related to the free proton, which is probably stable, or at least, take a lot of time for decay (1034+ year sequence). Free neutrons are unstable and half of the life of approximately 611 seconds are decayed. Their related antiparticles are expected to follow the same pattern, but they are difficult to catch and study, because they immediately destroy the contact of ordinary matter. The "bound" protons and neutrons contained within an atomic nucleus are generally considered to be stable. Experimental, the study of Hayden Physics is done by colliding protons or nuclei of heavy elements such as lead or gold, and particles produced are detected by debris in rain. In the environment, the collision of cosmic rays with environments produce onions such as mens.

Properties of Hadron

According to the quark model, the properties of the headron are predominantly determined by their so-called valence quark. For example, a proton is composed of two up quarks (each electric charge + 2, 3, total + 4, 3 together) and one down quark (electric charge - 1/3). Adding them together brings a proton charge of +1. Although quarks also charge color, nevertheless, the headphones have zero total color charge due to an event called color phenomenon. That is, the headphones should be "colorless" or "white". The simplest way to do this is with a color quark and an anticlock of the respective anticollars, or three quarks of different colors. The first arrangement headphones are a type of mason, and the other arrangement is a type of baron.

 

Large-scale virtual glues form numerical majority of particles inside the headphones. The force of strong force glosses which bind together the quarks, they have enough energy (e), in which echoes made from large scale (M) quarks (E> MC2). One result is that short-term pairs of virtual quarks and antiquarks are continuously formed and are disappearing inside a headroot again. Because virtual quarks are not static wave packets (quanta), but there is an irregular and transient phenomenon, it is not worthwhile to ask which quark is real and which is virtual; It is clear from the outside as just a small extra headron. Therefore, when a headron or anti-haydrone (usually) is said to be combined with 2 or 3 quarks, it technically refers to the continuous excess of quark versus anticarcus.

Like all sub-atomic particles, the quantum numbers are assigned to the headron which corresponds to the representation of the Poincaré group: JPC (M), where J spin is the quantum number, P internal internal parity (or P-parity, C) charge Conjugation (or c) -changes), and mass of particle. Note that the mass of a headron with its valence is very low with the mass of the quark; Rather, due to large scale energy equivalence, most of the mass is connected to a large amount of energy which is linked to strong interaction. Headrons may also take quantum numbers such as isosine (gi resemblance), and quaintity. All quarks are an additive, protected quantum number, called a baryon number (B), which is + 1arks3 for quark and 1 qu3 for antiquark. This means that the Barians (B1 = 1, Mixed particles made up of a large odd number of three, five or quarks) whereas B in the mons = 0.

Hadron known states as resonance to excited states. Each Ground State Hadron can have many upbeat states; Many hundreds of resonances have been observed in experiments. Echo resonates through strong nuclear force (within approximately 10 extremely24 seconds) decay.

Hadron may disappear at other stages of the case. For example, at a very high temperature and high pressure, as long as quarks do not have enough taste, the theory of quantum chromodynamics (QCD) predicts that quarks and gluons will no longer be restricted within the hydroone, because "strong The energy of the conversation decreases with energy. "This property, which is known as asymptomatic freedom, is experimental to 1 GV Betrenvolt) and 1 Tev (terrelronovolt) have been confirmed in the power range.

All free radars except the proton and antiprotin are unstable.

Baryons

Baron is a hydrone with an odd number of valence quark (at least 3). Most well-known baryons like Proton and Neutron have three valence quarks, but Pentakvark with three quarks - three quarks of different colors and an additional quark-anticarc pair are also present. Because there are quarks in odd numbers in the barriers, they are also all fermions, that is, they have half integer spin. Since quarques possesses the Baryan number B = 1arks3, the barriers have Bariange number B = 1.

Each type of beron has a uniform antipode, in which quarks are replaced by their respective antiquarks. For example, as a proton is made up of two up-quarks and a down-quark, its antiparticle, antiproton is made up of two up-anticarcos and a down-anticyclic.

By August 2015, there are two known pentaquarks, P +

c (4380) and P +

C (4450), both were searched by LHCB in 2015.

Mesons

Masons are Hurden, with the same number of valence quarks (at least 2). Most famous mesons are made from a quark-antericarch pair, but possible Tetraquark (4 quarks) and hexquark (6 quarks, in which one deuterian or three quark-anticarc pairs are included) can be discovered and confirming their nature There are many other fictitious types of foreign mason that may be present, which do not come within the quark model of classification. Lubol and Mason) bound by Hybrid Mason (turns Gluns.

Because the mesons have a similar number of quarks, they are all bosons, with integer spin, i.e., 0, 1, or .1 They have boron number B = 1/3 - 1 = 3 = 0. Examples of commonly produced mason in particle physics experiments include Pion and Kance. Pinus also plays the role of holding atomic nuclei simultaneously through an atomic nucleus.
