On the rise of the proton structure function F2 towards low x |
|
| Abstract: | A measurement of the derivative (∂ lnF2/∂ lnx)Q2≡−λ(x,Q2) of the proton structure function F2 is presented in the low x domain of deeply inelastic positron–proton scattering. For 5×10−5x0.01 and Q21.5 GeV2, λ(x,Q2) is found to be independent of x and to increase linearly with lnQ2. |
