In particle physics, a baryon is a type of composite subatomic particle, including the proton and the neutron, that contains an odd number of valence quarks, conventionally three. Baryons belong to the hadron family of particles; hadrons are composed of quarks. Baryons are also classified as fermions because they have half-integer spin.
In particle physics, a hadron is a composite subatomic particle made of two or more quarks held together by the strong interaction. They are analogous to molecules, which are held together by the electric force. Most of the mass of ordinary matter comes from two hadrons: the proton and the neutron, while most of the mass of the protons and neutrons is in turn due to the binding energy of their constituent quarks, due to the strong force.

Chen or Ch'en may refer to:
Chen was a state founded by the Duke Hu of Chen during the Zhou dynasty of ancient China. It existed from c. 1045 BC–479 BC. Its capital was Wanqiu, in present-day Huaiyang County in the plains of eastern Henan province. Chen, the 4th most popular Chinese surname in the world, and members of the Hu clan, the 13th most popular Chinese surname in the world, would claim descent from the Duke Hu of Chen who was in turn descended from the legendary Emperor Shun. At its peak, Chen encompassed fourteen cities in modern-day Henan and Anhui.
In physics, the eightfold way is an organizational scheme for a class of subatomic particles known as hadrons that led to the development of the quark model. Both the American physicist Murray Gell-Mann and the Israeli physicist Yuval Ne'eman independently and simultaneously proposed the idea in 1961. The name comes from Gell-Mann's (1961) paper and is an allusion to the Noble Eightfold Path of Buddhism.

The Xi baryons or cascade particles are a family of subatomic hadron particles which have the symbol Ξ and may have an electric charge of +2 e, +1 e, 0, or −1 e, where e is the elementary charge.

Shan is a Chinese surname. The origin of this surname is not clear. One explanation is that it came from Shan County in Shandong province. Another possible origin involves King Cheng of Zhou's youngest son's acquisition of the name when he was given what would become the Shan state when the enfeoffment system was enacted during the Zhou dynasty. The Shan state existed for a few hundred years before it was annexed by a stronger neighbouring state. It was located in present-day Jiyuan, Henan province. Although the surname comes from the place name, the Shan family was a branch of the royal family of the Zhou dynasty. Its ancient origin determines its rareness and not many people have the Shan surname. According to one unverifiable estimate, about 150,000 people are of the surname.
