The exponent λ (x, Q2) of the proton structure functionF₂(x, Q2) at lowx

摘要

The exponent λ of the structure function F₂ ∼x −λ is calculated using the solution of the DGLAP equation for gluon at lowx reported recently by the present authors. The quantity λ is calculated both as a function ofx at fixedQ 2 and as a function ofQ 2 at fixedx and compared with the most recent data from H1 Keywords DGLAP equation for gluon - method of characteristics - lowx - exponent of proton structure function PACS Nos 12.38.-t - 12.38.Bx - 13.60.Hb
