We show that using the full tower information in the form of an image,

a Convolutional Neural Network(CNN) can efficiently recognise Vector boson fusion(VBF)
signal from non VBF backgrounds at the Large Hadron Collider(LHC). As a concrete example, we compare with existing state-of-the-art techniques currently in use, we show that deep-learning algorithms like a CNN can significantly improve... -

Based on the jet image approach, which treats the energy deposition in each calorimeter cell as the pixel intensity, the Convolutional neural network (CNN) method has been found to achieve a sizable improvement in jet tagging compared to the traditional jet substructure analysis.

In this work, the Mask R-CNN framework is adopted to reconstruct Higgs jets in collider-like events, with the... -

During the upcoming Run 3, a new experimental program will be initiated at the LHC in its far-forward region that will focus on the search for highly-displaced decays of light unstable BSM particles in the FASER detector and on studying interactions of high-energy neutrinos in the FASERnu and SND@LHC experiments. To fully exploit the relevant physics potential, the experimental efforts should...

We present ARGES, a toolkit for obtaining renormalisation group equations in perturbation theory, as well as SARGES, its supersymmetric counterpart.

The programs can handle any perturbatively renormalisable four-dimensional quantum field theory, and have pioneered the approach of performing a symbolic rather than numeric computation. We highlight further notable features, such as input of... -

program automating the calculation of amplitudes, squared amplitudes and
Wilson coefficients at the tree level and the one-loop level for general
BSM models. This type of calculations requires a computer algebra system
and could only be done, up to now, using Mathematica that is a
commercial and closed software... -

We present FlexibleDecay, a tool to calculate decays of scalars in an arbitrary BSM model. The tool aims for high precision particularly in the case of Higgs boson decays. In the case of scalar and pseudoscalar Higgs boson decays the known higher order SM QED, QCD and EW effects are taken into account where possible. The program works in a modified MSbar scheme that exhibits a decoupling...

The new developments in SModelS, an automated tool enabling the fast interpretation of simplified model results from the LHC, make it possible to include a wide range of constraints for long-lived particles and treat them at the same footing as the constraints from prompt searches. We present these new features of SModelS v2.x and the new experimental analyses included in its database, and...
