Matching parton showers to NLO computations [PDF]
We give a prescription for attaching parton showers to next-to-leading order (NLO) partonic jet cross sections in electron-positron annihilation. Our method effectively extends to NLO the scheme of Catani, Krauss, Kuhn, and Webber for matching between m ...

Matching NLO QCD computations with PYTHIA using MC@NLO [PDF]
We present the matching between a next-to-leading order computation in QCD and the PYTHIA parton shower Monte Carlo, according to the MC@NLO formalism.

From dimensional regularization to NLO computations in four dimensions [PDF]
Loop-tree duality (LTD) allows to express virtual contributions in terms of phase-space integrals, thus leading to a direct mapping with real radiation terms. We review the basis of the method and describe its application to regularize Feynman integrals.

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 ...

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 ...

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.

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).

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.
