Solution of the multi-reggeon compound state problem in multi-colour QCD
G. P. Korchemsky, J. Kotanski, A. N. Manashov
We study the properties of the colour-singlet compound states of reggeized gluons in multi-colour QCD using their relation with noncompact Heisenberg spin magnets. Applying the met…
New predictions for inclusive heavy-quarkonium P-wave decays
N. Brambilla, D. Eiras, A. Pineda +2
We show that some NRQCD colour-octet matrix elements can be written in terms of (derivatives of) wave functions at the origin and non-perturbative universal constants once the fact…
Measuring effective electroweak couplings in single top production at the LHC
D. Espriu, J. Manzano
We study the mechanism of single top production at the LHC in the framework of an effective electroweak Lagrangian, analyzing the sensitivity of different observables to the magnit…
Prospects for supersymmetric charged Higgs boson discovery at the Tevatron and the LHC
Alexander Belyaev, David Garcia, Jaume Guasch +1
We investigate the prospects for heavy charged Higgs boson production through the mechanisms pp-bar(pp)->tbH+ +X at the upgraded Fermilab Tevatron and at the upcoming LHC collider…
Massive fields temper anomaly-induced inflation: the clue to graceful exit?
Ilya L. Shapiro, Joan Sola
A method of calculating the vacuum effective action for massive quantum fields in curved space-time is outlined. Our approach is based on the conformal representation of the fields…
Evolution equation for the structure function g_2(x,Q^2)
V. M. Braun, G. P. Korchemsky, A. N. Manashov
We perform an extensive study of the scale dependence of flavor-singlet contributions to the structure function g_2(x,Q^2) in polarized deep-inelastic scattering. We find that the…
