Large infra-red corrections in QCD processes

Improving the Infra-red of Holographic Descriptions of QCD

A surprisingly good holographic description of QCD can be obtained from naive five dimensional gauge theory on a truncated AdS space. We seek to improve the infra-red description of QCD in such models by using a more sophisticated metric and an action derived from string theory duals of chiral symmetry breaking. Our metric is smooth into the infra-red and the chiral condensate is a prediction o...

Second-order Approximate Corrections for QCD Processes

Electroweak & QCD corrections to Drell Yan processes

The relevance of single-W and single-Z production processes at hadron colliders is well known: in the present paper the status of theoretical calculations of Drell-Yan processes is summarized and some results on the combination of electroweak and QCD corrections to a sample of observ-ables of the process pp → W ± → µ ± + X at the LHC are discussed. The phenomenological analysis shows that a hig...

Infra-Red Plasmonic Sensors

Plasmonic sensors exploiting the localized surface plasmon resonance (LSPR) of noble metal nanoparticles are common in the visual spectrum. However, bio-sensors near the infra-red (NIR) windows (600–900 nm and 1000–1400 nm) are of interest, as in these regions the absorption coefficients of water, melanin deoxyglobin, and hemoglobin are all low. The first part of this paper reviews the work tha...

Infra – red soft universality

We show that in a special class of theories the commonly assumed universal form of the soft supersymmetry–breaking terms is approached in the infra–red limit. The resulting universal scalar mass and trilinear coupling are predicted in terms of the gaugino mass.
