On the Odderon Intercept in Qcd
The odderon singularity is studied in perturbative QCD in the framework of the Bartels-Kwieciński-Praszalowicz (BKP) equation. Arguments for the odderon intercept being exactly equal to unity are given. Besides, a variational method based on a complete system of one-gluon functions is presented. For the odderon, the highest intercept calculated by this method is 1 − (Ncαs/π) 0.45. Comparison to...
متن کاملOn the odderon intercept in perturbative QCD
Arguments are presented for the odderon intercept being exactly equal to unity. A variational method is presented based on a complete system of onegluon functions. For the odderon, the highest intercept calculated by this method is 1− (3αs/π) 0.45. March 1996 hep-ph/9603218 US-FT/7-96 ∗ Visiting Professor IBERDROLA.

متن کاملOn the odderon intercept in the variational approach
The odderon intercept α is recalculated by the variational method based on conformal invariance. The final result is α = 1 − 0.339 α s N/π in contrast to the published value above unity.

Glueball masses with J ≤ 7 are computed both for C = +1 and C = −1 using the string Hamiltonian derived in the framework of the Vacuum Correlator Method. No fitting parameters are used, and masses are expressed in terms of string tension σ and effective value of α s. We extend the calculations done for J ≤ 3 using the same Hamilto-nian, which provided glueball masses in good agreement with exis...
