Critical exponents and amplitude ratios of scalar nonextensive $q$-field theories. (arXiv:1810.02349v1 [hep-th])
来源于:arXiv
We compute the radiative quantum corrections to the critical exponents and
amplitude ratios for O($N$) $\lambda\phi^{4}$ scalar high energy nonextensive
$q$-field theories. We employ the field theoretic renormalization group
approach through six methods for evaluating the high energy nonextensive
critical exponents up to next-to-leading order while the high energy
nonextensive amplitude ratios are computed up to leading level by applying
three methods. Later we generalize these high energy nonextensive finite loop
order results for any loop level. We find that the high energy nonextensive
critical exponents are the same when obtained through all the methods employed.
The same fact occurs for the high energy nonextensive amplitude ratios.
Furthermore, we show that these high energy nonextensive universal quantities
are equal to their low energy extensive counterparts, thus showing that the
nonextensivity is broken down at high energies. 查看全文>>
