NLO computation of diffractive di-hadron production in a saturation framework [PDF]
Abstract The cross-sections of diffractive double hadron photo- or electroproduction with large pT, on a nucleon or a nucleus, are calculated to NLO accuracy. A hybrid formalism mixing collinear factorization and high energy small-x factorization, more precisely the shockwave formalism for the latter, is used to derive the results.

Matching NLO QCD computations with Parton Shower simulations: the POWHEG method [PDF]
The aim of this work is to describe in detail the POWHEG method, first suggested by one of the authors, for interfacing parton-shower generators with NLO QCD computations. We describe the method in its full generality, and then specify its features in two subtraction frameworks for NLO calculations: the Catani-Seymour and the Frixione-Kunszt-Signer ...

Non-line-of-sight (NLOS) imaging of hidden objects is a challenging yet vital task, facilitating important applications such as rescue operations, medical imaging, and autonomous driving. In this paper, we attempt to develop a computational steady-state NLOS localization framework that works accurately and robustly under various illumination conditions.

NLO ACTIVITY AND COMPUTATIONAL DISCUSSION OF HALOGEN-SUBSTITUTED CHALCONE DERIVATIVES
The four halogen-substituted chalcones 1–4 have been synthesized and analyzed to FT-Infrared, UV-Visible, GC-MS spectrometer, and 1D NMR (1H and 13C) spectroscopy techniques. Computational calculations were carried out for geometrical optimization of structure regards bond length, bond angle, and torsional angle estimated.

Computation of NLO processes involving heavy quarks using Loop-Tree Duality [PDF]
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 ...

Relic density computations at NLO: infrared finiteness and thermal correction [PDF]
Abstract There is an increasing interest in accurate dark matter relic density predictions, which requires next-to-leading order (NLO) calculations. The method applied up to now uses zero-temperature NLO calculations of annihilation cross sections in the standard Boltzmann equation for freeze-out, and is conceptually ...

Automation of NLO computations using the FKS subtraction method [PDF]
In this talk the FKS subtraction method for next-to-leading order (in QCD) computations is reviewed and its automation in the computer code MadFKS is presented. As a proof of concept, some results in the form of plots for distributions at next-to-leading order in e+e− → 2, 3 and 4 jets are shown by interfacing this code to BlackHat and Rocket.

Improving colour computations in MadGraph5_aMC@NLO and exploring a $$1/N_c$$ expansion [PDF]
AbstractIn this paper, we present an extension of which is able to evaluate tree-level QCD matrix-elements up to $$2\rightarrow 6$$ 2 → 6 (one more particle than before).
