A note on the BFKL pomeron and the 'hot spot' cross section

20 pp. (1993).
We comment on the numerical calculation of the Lipatov pomeron in the measurement of “hot spots” in deep inelastic scattering. We illustrate that previous analytic estimates based upon the leading term in the Lipatov equation are accurate within 20%. We present evidence that numerical calculations should be done with a fixed αs. The use of a running $α_s$ appears as an unnecessary complication. We argue that at low Q2 the BFKL pomeron requires higher-order corrections.
