The Physics

Take a look at the fundamental physics that support and guide the experimental data analysis searches -and discoveries- relative to Higgs candidates, predicted by the Standard Model of Particle Physics.

The Experiments

The ATLAS experiment at the LHC is a many-layered instrument designed to detect some of the tiniest yet most energetic particles ever created on earth. It consists of six different detecting subsystems wrapped concentrically in layers around the collision point to record the trajectory, momentum, and energy of particles, allowing them to be individually identified and measured.

The Data

Current open access ATLAS data is delivered by the ATLAS Open Data project for Education. The dataset consists of a series of ROOT-kind files containing real data recorded by the ATLAS Experiment at a centre-of-mass energy of 13 TeV. It also includes a set of simulated, Monte Carlo, samples ranging from very well-known Standard Model processes to some hypothetical Beyond Standard Model physics.

The Analyses

Three Higgs search analyses are presented. First, they study the decay of a Higgs boson into two other Standard Model bosons: W's, Z's and photons. Second, they exploit the full potential of the ATLAS detector to discriminate between leptons, photons and energy-unbalances called Missing Transverse Energy to reconstruct back the origin of such couple to a possible Higgs candidate.
