φ^4 theory in 1+d dimensions at high temperature: dimensional reductinon Fernández Álvarez-Estrada, Ramón The φ^4 theory in 1+d dimensions is analyzed at high temperatures in the imaginary-time formalism. General results are given for the leading high-temperature contributions to all renormalized Careen's functions. The latter are generated by a high-temperature partition function which describes another φ^4 theory in d spatial dimensions with special mass renormalizations. The triviality/nontriviality of the (φ^4)_1+3 theory is discussed briefiy. 2023-06-20T20:12:48Z 2023-06-20T20:12:48Z 2023-06-20T20:12:48Z 1987-10-15 journal article https://hdl.handle.net/20.500.14352/59851 0556-2821 10.1103/PhysRevD.36.2411 eng DE-AC03-76-SF00098 PHYS. 85-15857 AE86-0029 open access American Physical Society
