This paper summarises the work done by the ATLAS and CMS collaborations, and by the teams of the Large Hadron Collider at CERN, that led to the discovery of a new particle, with mass near 125 GeV and properties consistent with the ones predicted for the Standard Model Higgs boson. Geneva, 4 July 2022. Seeking New Particles with Long Lifetimes; Seeking Photons/Zs and Something Undetectable; Triggering: Advances in 2012. Results from CMS (left) and ATLAS (right) on various searches for the new particle being produced and decaying in particular ways. the ATLAS and CMS discovery, is that the strong interactions produce 4 light resonances identied with the Higgs doublet and EWSB proceeds through vacuum misalignment [14]. The Higgs boson mass m H has been measured independently by the ATLAS and CMS exper-iments using the Run 1 dataset in several decay channels. Confirming the electroweak Standard Model drove three major projects at CERN spanning three decades, culminating in the discovery of the Higgs boson on 4 July 2012. Based on further improvements of the data, this discovery has by now been acknowledged as the discovery of a Higgs particle.2

This Letter reports the results of a search for the SM Higgs boson using samples collected by the CMS experiment, comprising data recorded at s = 7 and 8 TeV. Many Americans will mark the country's birthday today, but science nerds will celebrate the tenth anniversary of the discovery of the Higgs Boson - also known as the 'God Particle' - on July 4th. Harvey Newman, the Marvin L. Goldberger Professor of Physics at Caltech and one of the leaders of the Caltech team, which is part of the Abstract: Results are presented from searches for the standard model Higgs boson in proton-proton collisions at sqrt (s) = 7 and 8 TeV in the Compact Muon Solenoid experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at 7 TeV and 5.3 inverse femtobarns at On 31 July, 2012, the ATLAS experiment submitted a scientific paper describing the discovery of a new particle consistent with the Higgs Boson to the journal Physics Letters B. In 2012, the ATLAS experiment (Aad et al.,2012) and the CMS experiment (Chatrchyan et al.,2012) claimed the discovery of the Higgs boson. On the scale that particle physicists use to describe the certainty of a discovery, one sigma means the results could be random fluctuations in the data, 3 sigma counts as evidence and a 5-sigma result is a discovery. Techniques and results of the re-discovery analysis of standard model Higgs boson decaying to two photons are presented. At 14 TeV and 1 fb-1, discovery of the SM Higgs boson is out of reach. The CMS collaboration also submitted a paper to the same journal about their Higgs results. Type Tribute to Thomas W.B. Matthew Chalmers captures a glimpse of particle physics great adventure. The discovery, announced this week at the 40th International Conference on High Energy Physics by the Compact Muon Solenoid (CMS) collaboration working at the Large Hadron Collider (LHC), the worlds largest and highest-energy collider located near Geneva, Switzerland, adds to understanding about how basic constituents of the universe interact, and A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H and H Z Z 4 decay channels.

The discovery of the long awaited Higgs boson is described using data from the CMS detector at the LHC. In the context of the Standard Model (SM) the assumption of one doublet of scalar fields gives rise to a scalar particle known as the Higgs boson. Translate PDF. In 2020, CMS and ATLAS saw one such interaction the rare decay of a Higgs to a second-generation cousin of the electron called the muon 1. Weber and his colleagues had the first sighting of a rare process in which three massive bosons shoot out from a collision in the LHC. Theres the famous paper in 1976 by Ellis, Gaillard and Dimopoulos that calculated how the Higgs might be observed, but in essence it said: why bother looking for this thing, we dont know where it is!
