Exact quantum Sine-Gordon soliton form factors

Soliton form factors are constructed using Zamolodchikov's proposed exact massive Thirring model S-matrix. The asymptotic behaviour of the electromagnetic form factor is $\text{～(?t)}{}^{\mathrm{<mtext>?</mtext><mtext>g</mtext><mtext>2</mtext>}}$. The quasiclassical limit is not the previously accepted result.
