Heterotic string theory - Wikipedia
In string theory, a heterotic string is a closed string (or loop) which is a hybrid ('heterotic') of a superstring and a bosonic string. There are two kinds of heterotic superstring theories, the heterotic SO (32) and the heterotic E 8 × E 8, abbreviated to HO and HE.
Heterosis - Wikipedia
Heterosis, hybrid vigor, or outbreeding enhancement is the improved or increased function of any biological quality in a hybrid offspring. An offspring is heterotic if its traits are enhanced as a result of mixing the genetic contributions of its parents.

Heterotic String Theory and Models - Nature
Heterotic string theory is a compelling framework in theoretical physics that combines elements of both superstring theory and gauge theories. It aims to unify the fundamental forces of nature and ...
Heterosis - PMC
Heterosis refers to the phenomenon that progeny of diverse varieties of a species or crosses between species exhibit greater biomass, speed of development, and fertility than both parents. Various models have been posited to explain heterosis, including dominance, overdominance, and pseudo-overdominance.

1985年1月1日 · The heterotic string theory is a theory of closed strings, in which the compactification of sixteen internal dimensions produces the gauge group SO (32) or E~ x E~*. Another motivation behind the construction of the heterotic string was the search for new consistent string theories.

The Heterotic String - SpringerLink
In this chapter we construct and study a new class of string theories: the heteroric ones which on the left side are the bosonic string and on the right one the superstring. Two of these theories are supersymmetric (16 supercharges) with spacetime gauge group \ ( Spin (32)\) and \ (E_8\times E_8\), respectively.
