6,7,8,9. The second type of coupling involves another fundamental interaction, the Yukawa interaction, between the Higgs boson and matter particles, or fermions. The third type of coupling is the ‘self-coupling’ of the Higgs boson
The primary vertex of the event, representing the hard interaction, is selected among the reconstructed vertices as the one with the highest sum of the transverse momenta squared of the tracks associated with it. 4.1 Selection of W boson events Events with a high- pT lepton from the W boson...
Plainly: the BM function is only nonzero because of the interaction between the eikonalised quark and the spectator – this is highlighted by the αIR/mG2 factor; it is nonzero in the chiral limit, mπ2=0, so long as the pion is a Goldstone boson; and the magnitude of the effect ...
In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts. Ten years later, and with the data corresponding to the production of a 30-times lar
Leptons are fundamental particles thatdon’t interact by the strong interaction, only the weak interaction. Electrons are stable leptons; muons are heavier leptons which decayinto electrons. There are alsoneutrinos:the electron neutrino and the muon neutrino, which have almost no mass and nocharge....
luminosity, high-energy accelerators will enable science to escape the limitations of a hundred-year focus on the proton and begin to probe deeply into the structure of the pion [1], [2], [3], [4], [5], [6], [7], [8], Nature's most fundamental Nambu-Goldstone boson [9], [...
Bose–Einstein condensation (BEC) is a fundamental phenomenon connected to superfluidity in liquid helium [1]. Its achievement in practice led to the first unambiguous manifestation of the existence of a macroscopic quantum state in a many particle system. Although the condensates of boson particles...
Searching for new particles beyond the standard model is crucial for understanding several fundamental conundrums in physics and astrophysics. Several hypothetical particles can mediate exotic spin-dependent interactions between ordinary fermions, which enable laboratory searches via the detection of the intera...

Electroweak symmetry breaking explains the origin of the masses of elementary particles through their interactions with the Higgs field. Besides the measurements of the Higgs boson properties, the study of the scattering of massive vector bosons with spi
