چکیده

We report on results for the heavy flavor contributions to F2(x,Q ) in the limit Q ≫ m at NNLO. By calculating the massive 3–loop operator matrix elements, we account for all but the power suppressed terms in m/Q. Recently, the calculation of fixed Mellin moments of all 3–loop massive operator matrix elements has been finished. We present new all–N results for the O(nf )–terms, thereby confirming the corresponding parts of the 3–loop anomalous dimensions. Additionally, we report on first genuine 3–loop results of the ladder–type diagrams for general values of the Mellin variable N .

( x , Q 2 ) for large virtualities

The heavy flavor contributions to unpolarized deep-inelastic structure functions are large in the region of small values of x, see e.g. [1]. At present they are known to O(αs) [2], while the anomalous dimensions and Wilson coefficients for the light parton contributions were calculated to O(αs) [3,4]. Since the scaling violations of the light parton and heavy flavor terms are different, the kno...

New Heavy Flavor Contributions to the DIS Structure Function

We report on recent results obtained for the massive Wilson coefficients which contribute to the structure function F 2 (x, Q 2) at O(α 3 s) in the region Q 2 /m 2 > ∼ 10. In the calculation new species of harmonic sums and harmonic polylogarithms generated by cyclotomic polynomials arise in intermediary results which are briefly discussed.

The Gluonic Operator Matrix Elements at O ( α 2 s ) for DIS Heavy Flavor Production

We calculate the O(αs) gluonic operator matrix elements for the twist–2 operators, which contribute to the heavy flavor Wilson coefficients in unpolarized deeply inelastic scattering in the region Q2 ≫ m2, up to the linear terms in the dimensional parameter ε, (D = 4+ε). These quantities are required for the description of parton distribution functions in the variable flavor number scheme (VFNS...

SFB / CPP – 07 – 11 March 2007 Two – Loop Massive Operator Matrix Elements and Unpolarized Heavy Flavor Production at Asymptotic Values Q 2 ≫

We calculate the O(αs) massive operator matrix elements for the twist–2 operators, which contribute to the heavy flavor Wilson coefficients in unpolarized deeply inelastic scattering in the region Q2 ≫ m2. The calculation has been performed using light–cone expansion techniques. We confirm an earlier result obtained in [1]. The calculation is carried out without using the integration-by-parts m...

Large Beyond–Leading–Order Effects in b → sγ in Supersymmetry with General Flavor Mixing

We examine squark–gluino loop effects on the process b → sγ in minimal supersymmetry with general flavor mixing in the squark sector. In the regime of heavy squarks and gluino, we derive analytic expressions for the beyond–LO corrections to the Wilson coefficients and find them to be often large, especially at large tanβ and μ > 0. The ensuing ranges of values of the Wilson coefficients are typ...
