A Light Higgs Boson Explanation for the g-2 CrisisAthanasios sakis DedesHoward Haber
The failure of the\(SU(2)\times U(1)\)theory for hadrons has its explanation in the simple fact that hadrons are not elementary articles. When the same idea is applied to anSU(2) doublet of quarks, it works perfectly. However, when Glashow wrote his paper in 1961, composite nucleon...
Editor's note: On October 8, 2013, Peter Higgs and Francois Englert won the Nobel Prize in Physics for their work on the Higgs boson. Below, our science columnist Brian Greene explains the science behind the discovery. A famous story in the annals of physics tells of a 5-year-old Albert...
This feature persists after the addition of a Higgs, W or Z/γ∗ boson to the scattering. Two simple examples are shown in figure 8. What is meant by the term "factorisation of the amplitude" is that the correct MRK limit of the amplitude can be obtained from a simple analytic ...
So far, all the mea- surements of the discovered new particle [3–10] are well com- patible with the scalar boson predicted by the Standard Model (SM) [11–15]. It is well known that the SM cannot be the final theory of nature. Theoretically, successful explanation of some prob- ...
Little Higgs models have an enlarged global symmetry which makes the Higgs boson a pseudo-Goldstone boson.This symmetry typically contains sponta-neously broken U(1) subgroups which provide light electroweak-singlet pseu-doscalars.Unless such particles are absorbed as the longitudinal component of Z′...
Note that for the explanation of the excesses it is not important if h3 is light, since only the mixing of h1 with the SM-like Higgs boson h2, providing the up-type doublet component of h1, is relevant. The parameter range for tanβ is not only the preferred range in the N2HDM...
We shall argue that such a Type-I 2HDM provides a simple explanation for all excesses, while being consistent with null results. The LEP results [4] are most simply understood as a type of scalar mixing with the Higgs boson at a level s2δ ∼ 0.1. However, this could be an SU(2)...
Higgs boson, particle that is the carrier particle, or boson, of the Higgs field, a field that permeates space and endows all elementary subatomic particles with mass through its interactions with them. The field and the particle—named after Peter Higgs
