Abstract
The LHC represents the current energy frontier in collider experiments. Its most notable result so far was the experimental discovery of the Higgs boson, by the ATLAS and CMS collaborations. It is also very well suited to explore the physics of the top quark, the heaviest known elementary particle, with a Yukawa coupling of order 1. The data collected by these experiments during the LHC Run II allowed the measurement of top and Higgs experimental results, which provide very stringent tests of the Standard Model expectations near the electroweak scale, and therefore likely windows into new physics. The present article discusses the most recent experimental highlights in this area.
Highlights
The Large Hadron Collider (LHC) [1] at CERN is the highest energy particle collider in operation
By the end of the LHC Run I, enough data had been accumulated to achieve a Higgs mass measurement with per mille precision (0.2%) [18], establish that the total Higgs boson yield was within 10% of SM expectations [19], and determine, with minimal additional assumptions, that the overall Higgs branching fraction into Beyond the Standard Model (BSM) decays is less than 34% at 95% Confidence Level (CL)
This paper highlights some of the most significant recent results from the ATLAS and CMS experiments in the areas of top-quark and Higgs physics. It should be clear from the above, that the experimental programmes of these experiments cover these important subjects in great depth, using the fantastic exploration machine which is the LHC
Summary
The Large Hadron Collider (LHC) [1] at CERN is the highest energy particle collider in operation. In its second physics run (Run II), which started in 2015 and wi√ll terminate at the end of 2018, it has been colliding protons at a centre of mass energy of s = 13 TeV. With these data, both experiments have been exploring the Standard Model of particle physics (SM) to an unprecedented degree. Two areas are of particular interest for experimental exploration at the LHC, and were the subject of this communication: measurements of the top quark and of the Higgs boson. The present article highlights some of the latest measurements published by the two collaborations in these areas
