We present the NLO QCD corrections to pp arrow right γγj production at hadron colliders. Our calculation includes contributions from the fragmentation of a hadronic jet into a highly energetic ...photon, and consequently allows the implementation of arbitrary infrared-safe photon isolation definitions. We compare different photon isolation criteria and perform a detailed study of the dependence of the γγj cross section on the photon isolation parameters.
The production of two bb¯ pairs is a prominent background for Higgs and New Physics searches in various extensions of the Standard Model. We present here the next-to-leading order QCD corrections to ...the quark induced subprocess using the GOLEM approach for the virtual corrections. We show that our result considerably improves the prediction and conclude that the inclusion of next-to-leading order effects is indispensable for reliable studies of bb¯bb¯ observables in hadronic collisions.
The production of two b-quark pairs is a prominent background for Higgs and New Physics searches in various extensions of the Standard Model. We present here the next-to-leading order QCD corrections ...to the quark induced subprocess using the GOLEM approach for the virtual corrections. We show that our result considerably improves the prediction and conclude that the inclusion of next-to-leading order effects is indispensable for reliable studies of four b-quark observables in hadronic collisions.

In this paper, we present a novel method for utilising wearable devices with Convolutional Neural Networks (CNN) trained on acoustic and accelerometer signals in smart manufacturing environments in ...order to provide real-time quality inspection during manual operations. We show through our framework how recorded or streamed sound and accelerometer data gathered from a wrist-attached device can classify certain user actions as successful or unsuccessful. The classification is designed with a Deep CNN model trained on Mel-frequency Cepstral Coefficients (MFCC) from the acoustic input signals. The wearable device provides feedback on three different modalities: audio, visual and haptic; thus ensuring the worker’s awareness at all time. We validate our findings through deployments of the complete AI-enabled device in production facilities of Mercedes-Benz AG. From the conducted experiments it is concluded that the use of acoustic and accelerometer data is valuable to train a classifier with the purpose of action examination during industrial assembly operations, and provides an intuitive interface for ensuring continued and improved quality inspection.
Many highly developed Monte Carlo tools for the evaluation of cross sections based on tree matrix elements exist and are used by experimental collaborations in high energy physics. As the evaluation ...of one-loop matrix elements has recently been undergoing enormous progress, the combination of one-loop matrix elements with existing Monte Carlo tools is on the horizon. This would lead to phenomenological predictions at the next-to-leading order level. This note summarises the discussion of the next-to-leading order multi-leg (NLM) working group on this issue which has been taking place during the workshop on Physics at TeV Colliders at Les Houches, France, in June 2009. The result is a proposal for a standard interface between Monte Carlo tools and one-loop matrix element programs.
