In this talk a study of differential cross sections for the production of three and four jets in multi-Regge kinematics is presented. The main focus lies on the azimuthal angle dependences in events with two forward/backward jets tagged in the final state. Furthermore, the tagging of one or two extra jets in more central regions of the detector with a relative separation in rapidity from each...

We present a new method to compute higher-order corrections to physical cross-sections, at Next-to-Leading Order and beyond. This method, based on the Loop Tree Duality, leads to locally integrable expressions in four dimensions. By introducing a physically motivated momentum mapping between the momenta involved in the real and the virtual contributions, infrared singularities naturally...

Recently ATLAS published new data on dilepton angular coefficients in Z-boson production at the energy 8 TeV. In particular the famous Lam-Tung relation was shown to be broken and NNLO QCD corrections could explain only a fraction of this phenomenon. We investigate properties of the dilepton angular distributions and Lam-Tung relation breaking within kT-factorization framework and confront...

I present estimates of the branching fractions in the non-leptonic
charmonium two-body decay rates for $B^0\rightarrow \psi(2S)\pi^0$
decay and the same decays of $B^+\rightarrow \psi(2S)\pi^+$,
$B^0\rightarrow \psi(2S)K^0$ and $B^+\rightarrow \psi(2S)K^+$.
These estimates are based on a generalized factorization approach
making use of leading order (LO) and next-to-leading order...

Some hard exclusive processes can be described in a framework of QCD collinear factorization.
The amplitudes of Deeply Virtual Compton Scattering (DVCS), its crossing counterpart Timelike
Compton Scattering (TCS) and the amplitudes of neutral light and heavy vector meson (VM) production
can be calculated as a convolution of hard coefficient functions and generalized parton distributions. ...
