Energy-Momentum Tensor of Cosmological Fluctuations during Inflation
F. Finelli, G. Marozzi, G. P. Vacca +1
We study the renormalized energy-momentum tensor (EMT) of cosmological scalar fluctuations during the slow-rollover regime for chaotic inflation with a quadratic potential and find…
QCD Corrections to Electroweak Vector Boson Scattering at Small Scattering Angles
Krisztian Peters, Gian Paolo Vacca
We investigate the role of a certain class of QCD corrections to electroweak vector boson scattering at small scattering angles and large energies. These are present since, from th…
The Process gamma* + p -> eta_c + X: A Test for the Perturbative QCD Odderon
J. Bartels, M. A. Braun, G. P. Vacca
The rates of inclusive photo- and electroproduction of the eta_c meson: gamma* + p -> eta_c + X are calculated in the triple Regge region, integrated over the diffractive mass X. F…
Jet Vertex in the Next-to-Leading log(s) Approximation
G. P. Vacca
The next-to-leading corrections to the jet vertex which is relevant for the Mueller-Navelet jets production in hadronic collisions and for the forward jet cross section in lepton-h…
The Inflaton and Time in the Matter-Gravity System
A. Tronconi, G. P. Vacca, G. Venturi
The emergence of time in the matter-gravity system is addressed within the context of the inflationary paradigm. A quantum minisuperspace-homogeneous minimally coupled inflaton sys…
