Regge behaviour of structure functions and DGLAP evolution equation in leading order

In this paper, we find the t and x-evolution of deuteron structure function from DGLAP evolution equation of singlet structure function in leading order at small-x assuming the Regge behaviour of the singlet structure function at this limit and we compare our result of deuteron structure function with New Muon Collaboration data to find the range of the intercept of Regge behaviour for deuteron structure function. We also discuss the limitations of Taylor series expansion method in the Regge behaviour of structure function.
