The DIS crosssections ratio $R= \sigma_L/\sigma_T$ at small x from HERA data
Abstract
We extract the deep inelastic scattering crosssections ratio $R= \sigma _L/\sigma _T$ in the range $10^{4} \leq x \leq 10^{1}$ from $F_2$ HERA data using very simple relations based on perturbative QCD. The result depends on only one parameter $\delta$, being $x^{\delta}$ the behavior of the parton densities at low $x$, which has been determined recently with a good accuracy by the H1 group.
