Influence of light-quark masses in dynamical scale breaking

Creators

Description

It is demonstrated that light quark masses may significantly contribute to the logarithmic scale breaking in deep inelastic eletromagnetic lepton-nucleon scattering. This is mainly due to the combination of scale variables appearing in structure function equation together with larger 'current' masses for u and d quarks, recently reported in the literature.

Abstract (Portuguese)

Demonstra-se que massas de quarks leves podem contribuir significantemente a quebra de escala logaritmica no espalhamento lepton-nucleon eletromagnetico muito inelastico. Isso e devido principalmente a combinacao de variaveis de escala aparecendo na equacao de funcao de estrutura, junto com massas de correntes maiores para os quarks u e d, recentemente reportados na literatura.
