Scientific paper

It is suggested that the cosmological constant today be identified with the one provided by gauge theories at T = 3 K and not T = 0 K or T = 1015 K as done so far. We then calculate Λ(3 K) in the σ-model, Weinberg-Salam model and Mohapatra and Sidhu model. While an acceptable value is obtained with the rather ideal σ-model, a very small Λ is obtained with the WS model. For the MS model, Λ can be fitted only if at least one of the Higgs mesons has a very light mass (~3 K).
