Abstract：
We constructed a new model of D=4 heterotic string with the gauge group[ SU(2)] ⁶, which consists of the right-movers of the D=4 fermionic string and the left-movers of the D=10 N-S bosonic string. The massless ground state of the string contains the 4 dimensional supergravity multiplet and the super-Yang-Mills gauge field multiplet. The new model is tachyon-free, Lorentz invariant and supersymmetric.
