Subtraction terms for one-loop amplitudes with one unresolved parton

, 2003
Fully differential next-to-next-to-leading order calculations require a method to cancel infrared singularities. In a previous publication, I discussed the general setup for the subtraction method at NNLO.

Strategies for enhancing quantum entanglement by local photon subtraction [PDF]

Phys. Rev. A 87, 022313 (2013), 2012
Subtracting photons from a two-mode squeezed state is a well-known method to increase entanglement. We analyse different strategies of local photon subtraction from a two-mode squeezed state in terms of entanglement gain and success probability. We develop a general framework that incorporates imperfections and losses in all stages of the process ...

Inducing and Enhancing Antimicrobial Activity of Mining-Soil-Derived Actinomycetes Through Component Modification of Bennett’s Culture Medium

Microbiology Research
This study investigated the effect of different culture agar media, derived from Bennett’s medium, on the antimicrobial activity of 15 Streptomyces sp. and 1 Lentzea sp. strains isolated from mining environments. The media were prepared from the standard

An alternative subtraction scheme for next-to-leading order QCD calculations [PDF]

, 2010
We propose a new subtraction scheme for next-to-leading order QCD calculations. Our scheme is based on the momentum mapping and on the splitting functions derived in the context of an improved parton shower formulation. Compared to standard schemes, the new scheme features a significantly smaller number of subtraction terms and facilitates the matching

Antenna subtraction for gluon scattering at NNLO

, 2010
We use the antenna subtraction method to isolate the double real radiation infrared singularities present in gluonic scattering amplitudes at next-to-next-to-leading order.

General formulation of the sector-improved residue subtraction

, 2014
The main theoretical tool to provide precise predictions for scattering cross sections of strongly interacting particles is perturbative QCD. Starting at next-to-leading order (NLO) the calculation suffers from unphysical IR-divergences that cancel in ...

Antenna subtraction at NNLO [PDF]

Journal of High Energy Physics, 2005
The computation of exclusive QCD jet observables at higher orders requires a method for the subtraction of infrared singular configurations arising from multiple radiation of real partons. We present a subtraction scheme relevant for NNLO perturbative calculations in $e^+e^- \to $ jets.
