PhotonPortal

Shedding light on physics beyond the Standard Model at the LHC Run 2 using photons

PhotonPortal is an All-Knowledge Challenge project funded by the French National Research Agency (ANR) for the 2016-2020 period, and a collaboration of the ATLAS Experiment groups of LAPP Annecy-le-Vieux, LPNHE Paris and LAL Orsay.

Project

The Project

The discovery of the Higgs boson at the LHC Run 1 represents a milestone of particle physics. On the other hand, no clear sign of new phenomena beyond the Standard Model was found in the proton-proton (pp) collisions collected at 7 and 8 TeV at the LHC. The LHC Run 2 started in 2015, and by the end of 2016 ATLAS already collected 40 fb-1 of pp collisions at 13 TeV. The increased center of mass energy with respect to Run 1 has allowed ATLAS to search for new physics directly by looking for new particles, and will permit, in the years to come, to reveal New Physics through precision studies in the Higgs boson sector.

Final states involving photons will play an crucial role!

Di-photon events will be used to search additional Higgs-boson-like particles, while topologies with non-resonant photon pairs or single photons in presence of missing transverse energy will probe more exotic scenarios. In parallel, the study of the production of the Higgs boson associated with other objects represents an excellent opportunity to discover new physics: by exploiting the di-photon decay channel it will be possible to cleanly isolate the Higgs boson signal in events with additional objects, and to explore the possibility of its resonant or non-resonant production in association with new particles. With the full Run 2 dataset, about 100 fb-1 of pp collisions at 13 TeV, the PhotonPortal project plans to complete a rich and diverse program of searches and precision measurement exploiting photons in the final state as unifying element.

Team

The team behind the PhotonPortal project

We are a group of experimental physicists working on the ATLAS experiment in three French CNRS/INP23 laboratories. We played a fundamental role in the discovery of the Higgs boson and in the measurement of its properties and rare decays. We have a leading position in the ATLAS H→γγ and photon-related physics activities, and maintain a strong involvement in the ATLAS LAr electromagnetic calorimeter.
