We resum to next-to-leading order the distribution in the ratio of the invariant hadron mass mX to the total hadron energy EX and the distribution in mX in the semileptonic decays B → Xulν. By expanding our formulas, we obtain the coefficients of all the infrared logarithms at O(αS) and of the leading ones at O(α 3 S). We explicitly show that the relation between these semileptonic spectra and ...

Let Γg,n, for 2g − 2 + n > 0, be the Teichmüller group of an n-punctured genus g compact Riemann surface Sg,n and let Γ̂g,n be its profinite completion. There is a natural homomorphism from the Galois cohomology of Γ̂g,n, with coefficients in a discrete torsion Γ̂g,n-module, to the cohomology of the discrete group Γg,n, with induced coefficients. The main result of this paper is that this map is a...

The paper assumes a continuum of two period-lived agents; agents are identical except for inherited income. Young agents allocate their inheritance between consumption and investment in human capital under uncertainty. In the second period they receive a wage proportional to the accumulated human capital and invest in offspring. Two main results arise: a low earning per unit of human capital le...
