We study the squeezing and the quasiprobability distribution Q-function for an extended two-photon Jaynes-Cummings model (JCM) that includes atomic motion and the field mode structure. A comparative study of this model with respect to the standard model (in which the atom is at rest) has been presented here to isolate the effect of limited atom-radiation interaction time.

The Standard Model

By adding scalars, the Zee model, as standard model byond, has generated masses for the neutrinos. Due to the addition of new scalars, the mass spectrum and physical states of the particles are different from ones of the standard model. Using general Lagrangian, the interactions of gauge bosons with fermions and Higgs bosons are given. These vertices are the basis for the study of decay processes such as: lepton flavor violating Higgs decays, Higgs decays to two photon.

Photon Interactions

Ultraperipheral collisions (UPCs) of heavy ions and protons are the energy frontier for electromagnetic interactions. Both photonuclear and two-photon collisions are studied at collision energies that are far higher than those available elsewhere. In this review, we discuss physics topics that can be addressed with UPCs, including nuclear shadowing, nuclear structure, and searches for physics beyond the Standard Model.

Boson Coupling

We introduce a simple framework to estimate the composite Higgs boson coupling to two-photon in technicolor extensions of the standard model. The same framework allows us to predict the composite Higgs to two-gluon process. We compare the decay rates with the standard model ones and show that the corrections are typically of order one. We suggest, therefore, that the two-photon decay process can be used to disentangle a light composite Higgs from the standard model one. We also show that the Tevatron results for the gluon–gluon fusion production of the Higgs either exclude the techniquarks to carry color charges to the 95% confidence level, if the composite Higgs is light, or that the latter must be heavier than around 200 GeV.

The four detectors ALEPH, DELPHI, L3 and OPAL have collected ≈550,000 Z0 decays during the LEP run in 1990. We have made model-independent simultaneous fits to the LEP data to determine the Z0 parameters. The mass and widths of Z0 are Mz=91.177± 0.006±0.02 (LEP) GeV , Γz=2.481±0.010 GeV , Γ had =1.734±0.010 GeV and Γ lept =83.0 ± 0.4 MeV . The number of ν families is determined to be Nν=3.01±0.05. Simultaneous fits are performed within the Standard Model framework to the LEP data and constraining the value of sin 2 θw from the [Formula: see text] colliders we get the following values for top mass, electroweak mixing angle sin 2 θw and the radiative correction [Formula: see text], sin 2 θw=0.230±0.004 and ∆r=0.056±0.011.

The Standard Model

At the 1958 meeting of our society, then known as EMSA, the author introduced the concept of microspace and suggested its use to provide adequate information storage space and the use of electron microscope techniques to provide storage and retrieval access. At this current meeting of MSA, he wishes to suggest an additional use of the power of the electron microscope.The author has been contemplating this new use for some time and would have suggested it in the EMSA fiftieth year commemorative volume, but for page limitations. There is compelling reason to put forth this suggestion today because problems have arisen in the “Standard Model” of particle physics and funds are being greatly reduced just as we need higher energy machines to resolve these problems. Therefore, any techniques which complement or augment what we can accomplish during this austerity period with the machines at hand is worth exploring.
