What is a baryon number?
A baryon number is a quantum number related to the difference between the numbers of quarks and antiquarks in a system of subatomic particles.
What hold 3 quarks together?
There quarks are held together to make up protons and neutrons. They are held together by the strong force (one of the four fundamental forces.) The strong force is created by the quarks exchanging force carrier particles called gluons.
Does neutrino mean neutron?
Definatly not! A Neutron is a kind of Baryon (a type of Hadron) made up of the subatomic particles: Up quark, Down quark and Electrons. Now a Neutrino is different, there are three different types. There are Electron Neutrinoes, Muon Neutrinoes, and Tau Neutrinoes. Neutrinos are a type of Lepton, for every Neutrino there is a equivalent non-neutrino. For example, There is an Electron and an Electron Neutrino. So to conclude Neutrino does not mean Neutron, instead it is describing a type of Lepton. This should answer the Question.

How was the earth hypothesized to be formed?
In the most common versions, the universe was filled homogeneously and isotropically with a high energy density, high temperatures and pressures, and was expanding and cooling. 10-37 seconds into the expansion, a phase transition caused a cosmic inflation, which the Universe grew. After the inflation stopped, the universe consisted of a quark-gluon plasma and other particles. The temperatures were so high that the random motions of the particles were at relativistic speeds, and particle-antiparticle pairs were being created and destroyed in collisions. At some point an unknown reaction called baryogenesis violated the conservation of baryon numbers, leading to a small excess of quarks and leptons over anti quarks and antileptons- of the order of one part in 30 million. This resulted in the the predominance of matter over antimatter in the universe. The Universe continued to grow in size and fall in temperature, hence the typical energy of each particle was decreasing. Symmetry breaking phase transitions put the fundamental forces of physics and the parameter of elementary particles into their present form. After 10-11 seconds, the picture becomes less speculative, since the particle energies drop to values that can be attained in particle physics experiments. At about 10-6 seconds, quarks and gluons form baryons like protons and neutrons. The excess of quarks over antiquarks led to a small excess of baryons over antibaryons. The temperatures were no longer high enough to create new proton-antiproton pairs, so a mass annihilation immediately followed, leaving just 1 in 1010 of the original protons and neutrons, and one of their antiparticles. A similar process happened at about 1 second for electrons and positron's. After these annihilations, the remaining protons, neutrons and electrons were no longer moving relativistically and the energy density of the Universe was dominated by photons. a few minutes into the expansion, when the temperature was about a billion kelvins and the density was about that of air, neutrons combined with protons to form the Universe's deuterium and helium nuclei in a process called Big Bang nucleosyntheses. Most protons remained uncombined as hydrogen nuclei. As the Universe cooled, the mass energy density of matter came to gravitationally dominate the photon radiation. After about 376,000 years the electrons and nuclei combined into atoms hence the radiation decoupled from matter and continued through space largely unimpeded. This relic radiation is known as the cosmic microwave background radiation. When the Big Bang was done, and Earth was created, the continents that we know now, were conjoined together, which scientists call Pangaea. Then 180 million years ago, Pangaea broke apart, making two continents that were called Gondwana and Laurasia. And The two eventually broke apart to the continents that we know today.

What is the baryon number of an antiproton?
It is -1 as it the opposite of the baryon number of a proton.
What is an electronic that starts with b?
Baryon
What is a baryon number?
A baryon number is a quantum number related to the difference between the numbers of quarks and antiquarks in a system of subatomic particles.
What is a xi baryon?
A xi baryon is a subatomic hadron particle comprising three quarks, one up or down quark, and two heavier quarks.
What is a baryon acoustic oscillation?
Baryon acoustic oscillations are sound waves that traveled through the early universe, leaving behind a pattern of baryon (normal matter) density fluctuations. These fluctuations are observed in the distribution of galaxies and provide a standard ruler for measuring the expansion rate of the universe. Baryon acoustic oscillations are a key tool for studying the large-scale structure of the cosmos and probing the nature of dark energy.
What is the quark structure of a baryon?
A baryon is made up of three quarks. There are two types of baryons: protons, which consist of two up quarks and one down quark, and neutrons, which consist of one up quark and two down quarks. Quarks are elementary particles that are held together by the strong nuclear force to form protons and neutrons within the atomic nucleus.
Is a kaon a baryon?
No, a kaon is a meson, not a baryon. Baryons are particles composed of three quarks, while mesons are composed of a quark and an antiquark. Kaons contain a strange quark and an anti-up or anti-down quark.
What is a particle with three quarks?
A baryon: Protons, neutrons, and other odd combinations of quarks.
What is a biquark?
A biquark is another name for a diquark - a hypothetical state of two quarks grouped inside a baryon.
What is a BAO?
A BAO is a baryon acoustic oscillation - one of the periodic fluctuations in the density of the visible baryonic matter of the universe.
Can one neutron can split into an alpha particle and a beta particle?
No, this is not possible. There are multiple reasons one could give for this. For example electric charge is not conserved; the neutron has no charge, the beta particle has a charge of -1 (times the positive elementary charge) and the alpha particle has a charge of +2. Therefore you go from 0 charge to (-1 + 2 = 1) +1 charge. You could fix this by making two beta particles (but it would still not work for the reasons below). Every such reaction must conserve baryon number. A baryon is an object consisting of three quarks. The neutron is a baryon and therefore has baryon number +1. The alpha particle consists of two neutrons and two protons (the proton is also a baryon) so it has baryon number +4. The beta particle has baryon number 0. So the reaction n -> alpha + beta would increase the total baryon number by (+4 - 1 = 3) 3 which is not allowed. To fix this one would need, for example, to add three baryons to the initial state. The lepton number is also not conserved by this reaction. Protons and neutrons both have lepton number 0, but the beta particle has lepton number +1. Therefore this reaction would go from lepton number 0 to +1, which is also not allowed. This could be easily fixed by adding an antielectron-neutrino to the final state. A possible reaction that would fix everything would be something like: 4n -> alpha + 2 beta + 2 antielectron-neutrinos
