The High-Luminosity LHC will see pileup levels reaching 200, which will greatly increase the complexity of the tracking component of the event reconstruction. To reach out to Computer Science specialists, a Tracking Machine Learning challenge (TrackML) was set up on Kaggle in 2018 by a team of ATLAS, CMS and LHCb physicists, tracking experts and Computer Scientists, building on the experience of the successful Higgs Machine Learning challenge in 2014.

The High-Luminosity LHC (HL-LHC) is expected to reach unprecedented collision intensities, which in turn will greatly increase the complexity of tracking within the event reconstruction. To reach out to computer science specialists, a tracking machine learning challenge (TrackML) was set up on Kaggle by a team of ATLAS, CMS, and LHCb physicists tracking experts and computer scientists building on the experience of the successful Higgs Machine Learning challenge in 2014.

To attain its ultimate discovery goals, the luminosity of the Large Hadron Collider at CERN will increase so the amount of additional collisions will reach a level of 200 interaction per bunch crossing, a factor 7 w.r.t the current (2017) luminosity. This will be a challenge for the ATLAS and CMS experiments, in particular for track reconstruction algorithms. [...]

/LHCb
One of the most important aspects of data analysis at the LHC experiments is the particle identification (PID). In LHCb, several different sub-detectors provide PID information: two Ring Imaging Cherenkov (RICH) detectors, the hadronic and electromagnetic calorimeters, and the muon chambers. [...]

Charged particle track reconstruction is a major component of data-processing in high-energy physics experiments such as those at the Large Hadron Collider (LHC), and is foreseen to become more and more challenging with higher collision rates. A simplified two-dimensional version of the track reconstruction problem is set up on a collaborative platform, RAMP, in order for the developers to prototype and test new ideas. [...]

Heavy Flavour prospects at the HL-LHC On behalf of the ATLAS, CMS and LHCb Collaborations
/ Derkach, Denis (Higher Sch. of Economics, Moscow ; Yandex Sch. Data Anal., Moscow)
/ATLAS ; CMS ; LHC
The development of flavour physics has been impetuous in recent years: there
have been discoveries of CP violation in different B-meson systems, detailed
studies of mixing effects in neutral B and D mesons, and observation of rare
decays with unprecedented sensitivities. New discoveries can be expected for
larger samples available in the near future. [...]
