Visible matter, also called baryonic matter, consists of baryons — an overarching name for subatomic particles such asprotons, neutrons and electrons. Scientists only speculate what dark matter is made of. It could be composed of baryons but it could also be non-baryonic, which means consisting...
The antiparticle of a proton is the antiproton. It has the same mass as a proton however its charge is negative while the charge of protons is...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
A cell, a DNA molecule, an atom. Which one has the largest particle? Suspensionhas the largest particles. Are neutrinos proven? But we're not.Neutrinos are real. They're an essential part of physics, shedding light on the origin of mass, the particle-antiparticle asymmetry of the universe...
Does every particle have an antiparticle? Is a lepton an elementary particle? What is the positron decay equation? Is a proton a subatomic particle? How are positrons made? Are all baryons are protons? Is a neutron a subatomic particle? Is positron decay the same as gamma decay? How do...

Antimatter may seem impossibly far from daily lives. Butordinary bananas produce antimatter, releasing one positron—the antimatter equivalent of an electron—about every 75 minutes. Neutrinos may be their own antiparticles. A matter particle and its antimatter partner carry opposite charges, making th...
Why is the universe not made up of equal parts of matter and antimatter (Sakharov1967), as the Big Bang produced an equal mixture of both? [Baryogenesis, baryon asymmetry] Why is there an anomaly appearing in the cosmic microwave background radiation which appears to give special significance...
Due to the large separation between proton and neutron in deuteron [14], it can be safely regarded as a molecular state. Of course, the dibaryon state may also be a more exotic compact six quark structure, that is, the state cannot be represented by two well separated color singlet quark...
More specifically: what determines the relative production rates of baryons, which contain three valence quarks, and mesons, which consist of a quark and an antiquark? In electron–positron, electron–proton and proton–proton collisions, where a small number of particles is produced, the hadron...
