Particle Physics after the Higgs-Boson Discovery: Opportunities for the Large Hadron Collider
نویسندگان
چکیده
The first run of the Large Hadron Collider at CERN brought the discovery of the Higgs boson, an apparently elementary scalar particle with a mass of 125 GeV, the avatar of the mechanism that hides the electroweak symmetry. A new round of experimentation is beginning, with the energy of the proton–proton colliding beams raised to 6.5 TeV per beam, from 4 TeV at the end of the first run. This article summarizes what we have learned about the Higgs boson, and calls attention to some issues that will be among our central concerns in the near future.

Measurements of the Properties of the Higgs Boson Using the Atlas Detector
In July 2012, the ATLAS [1] and CMS Collaborations announced the discovery of a new particle [2, 3] at the Large Hadron Collider (LHC) at CERN in the context of the search for the Higgs boson of the Standard Model of Particle Physics (SM). Since then, with an increased dataset, improved detector understanding and refined analysis strategies, a wide range of properties of this new particle has b...
متن کاملOn Higgs mass generation mechanism in the Standard Model
The mass-generation mechanism is the most urgent problem of the modern particle physics. The discovery and study of the Higgs boson with the Large Hadron Collider at CERN are the highest priority steps to solve the problem. In this paper, the Standard Model Higgs mechanism of the elementary particle mass generation is reviewed with pedagogical details. The discussion of the Higgs quadric self-c...
متن کاملPerspective on This Week’s Announcement in High Energy Particle Physics and the Mechanism of Gauge Symmetry Breaking
This week, the Large Hadron Collider at CERN announced the discovery of a new boson with mass of ~125 GeV. Many have interpreted these results as evidence in favor of the Higgs boson believed to provide a mechanism for subatomic particle mass generation. However, CERN stated in their announcement that the true identity of the new boson, if confirmed, has yet to be determined. In this article, I...
متن کاملStandard Model Higgs Searches at the LHC
The Higgs mechanism [1] is central to the Standard Model of particle physics (SM). The existence of the Higgs field maintains the theory weakly interacting up to high energy scales and prevents some processes from violating unitarity. In the process of spontaneous breaking of electroweak symmetry, the weak bosons W and Z, as well as leptons and quarks, acquire mass through interactions with the...
متن کاملHiggs Boson Discovery with Boosted Trees
The discovery of the Higgs boson is remarkable for its importance in modern Physics research. The next step for physicists is to discover more about the Higgs boson from the data of the Large Hadron Collider (LHC). A fundamental and challenging task is to extract the signal of Higgs boson from background noises. The machine learning technique is one important component in solving this problem. ...
