Critical exponents of the O(N)-symmetric $$\phi ^4$$ ϕ 4 model from the $$\varepsilon ^7$$ ε 7 hypergeometric-Meijer resummation
Abstract We extract the $$\varepsilon $$ ε -expansion from the recently obtained seven-loop g-expansion for the renormalization group functions of the O(N)-symmetric model. The different series obtained for the critical exponents $$\nu ,\ \omega $$ ν , ω and $$\eta $$ η have been resummed using our...
