The 750 GeV diphoton excess in particle physics was an anomaly in data collected at the Large Hadron Collider (LHC) in 2015, which could have been an indication of a new particle or resonance. [8] [9] The anomaly was absent in data collected in 2016, suggesting that the diphoton excess was a statistical fluctuation.
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. [ 1 ] [ 2 ] It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories across more than 100 countries.

The Large Hadron Collider at CERN was designed to test the existence of the Higgs boson, an important but elusive piece of knowledge that had been sought by particle physicists for over 40 years. A very powerful particle accelerator was needed, because Higgs bosons might not be seen in lower energy experiments, and because vast numbers of ...
The Large Hadron Electron Collider (LHeC) is an accelerator study for a possible upgrade of the existing LHC storage ring – the currently highest energy proton accelerator operating at CERN in Geneva.
LHC@home is a volunteer computing project researching particle physics that uses the Berkeley Open Infrastructure for Network Computing (BOINC) platform. [2] The project's computing power is utilized by physicists at CERN in support of the Large Hadron Collider and other experimental particle accelerators.
The graph attention network (GAT) was introduced by Petar Veličković et al. in 2018. [11] Graph attention network is a combination of a GNN and an attention layer. The implementation of attention layer in graphical neural networks helps provide attention or focus to the important information from the data instead of focusing on the whole data.
In the field of particle physics, ATLAS studies different types of processes detected or detectable in energetic collisions at the Large Hadron Collider (LHC). For the processes already known, it is a matter of measuring more and more accurately the properties of known particles or finding quantitative confirmations of the Standard model .
This is a list of experiments at CERN's Large Hadron Collider (LHC). The LHC is the most energetic particle collider in the world, and is used to test the accuracy of the Standard Model, and to look for physics beyond the Standard Model such as supersymmetry, extra dimensions, and others.
