The smallness of the cosmological constant and the principle of naturalness

Малость космологической постоянной и принцип естественности

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

Within the framework of inflationary cosmology, we give temperature-dependent values of the cosmological constant Λ, the value Λ(2.7 K) of which is compatible with the present observational upper limit. We find that the smallness of Λ is theoretically as well as phenomenologically natural.

Riassunto

Nel sistema della cosmologia inflazionaria, si danno valori della costante cosmologica Λ dipendenti dalla temperatura, il valore Λ (2.7 K) della quale è compatibile con il presente limite superiore di osservazione. Si trova che la piccolezza di Λ è naturale sia dal punto di vista teorico che da quello fenomelogico.

Резюме

В рамках расширяющейся космологии мы приводим зависящие от температуры величины для космологической постоянной Λ. Величина Λ (2.7 К) сопоставима с наблюдаемым верхним пределом. Мы получаем, что малость величиы Λ является теоретическим следствием, а также представляет феноменологически естественный результат.
