The wavenumber-dependent, static dielectric function of classical charged fluids near freezing is obtained from structural data based on computer simulation or neutron diffraction, and its behavior is connected with the freezing process.  相似文献

We explore through two simple models, the first in which scalars are treated as fundamental and the second in which they are composite objects, the possibility that representations containing doubly charged scalars may participate in the spontaneous breakdown of the SU(2) × U(1) symmetry of electroweak interactions. We show that such exotic Higgs bosons may posses unsuppressed coupling to pairs of gauge vector bosons and comment on the observability of these charged Higgs bosons through the Cahn-Dawson mechanism in high-energy hadron colliders.  相似文献

Summary It is pointed out that in order to understand high-T c superconductivity, we need to study charged bosons in a disordered environment. In honour of Prof. Fausto Fumi on the occasion of his retirement from teaching.  相似文献

A new chain diagram formula is derived for many-body systems in such a way that an ideal gas term does not explicitly appear. This form is simpler and more convenient than the previously known expression. The result is applied to a charged boson gas under different conditions. It is found that exponential type decrease of the correlations for large distances changes into 1/r8 type decrease at the transition point.  相似文献

We searched for pair production of charged Higgs bosons via e+e annihilation, using data (23.3 pb) collected by the TOPAZ detector in the energy range . We observed no evidence for charged Higgs pair production and extended the excluded region in the MH±---BR (hadron) plane. The 95% CL lower mass limit is the most stringent for BR (hadron) = 0.6, giving mH±<22 GeV.  相似文献

Non-relativistic bosons interacting with Coulomb forces are unstable, as Dyson showed 20 years ago, in the sense that the ground state energy satisfiesE 0AN 7/5. We prove that 7/5 is the correct power by proving thatE 0BN 7/5. For the non-relativistic bosonic, one-component jellium problem, Foldy and Girardeau showed thatE 0CN1/4. This 1/4 law is also validated here by showing thatE 0DN1/4. These bounds prove that the Bogoliubov type paired wave function correctly predicts the order of magnitude of the energy.Work partially supported by U.S. National Science Foundation grant DMS 8600748Work partially supported by U.S. National Science Foundation grant PHY85-15288-A01Work supported by Alfred Sloan Foundation dissertation fellowship  相似文献

A search for pair produced charged Higgs bosons has been performed in the high energy data collected by DELPHI at LEP with , 172 and 183 GeV. The analysis uses the τντν, and final states and a combination of event shape variables, di-jet masses and jet flavour tagging for the separation of a possible signal from the dominant W+W and QCD backgrounds. The number of selected events has been found to be compatible with the expected background. The lower excluded value of the H± mass obtained by varying the H±→ hadrons decay branching ratio has been found to be 56.3 GeV/c2.  相似文献

For a model with the SU(2)L×SU(2)R×U(1){B−L} gauge group, the passage of neutrino flux through a substance is studied. It is shown that Higgs charged physical bosons can considerably change the potential of neutrino interaction with the solar substance. An analytical expression for the survival probability of left-handed electron neutrinos is derived in the two-flavor approximation. Yanka Kupala Grodno State University.

The probabilities of the associated production of a Higgs boson with a Z boson by a charged lepton in the field of a plane electromagnetic wave of arbitrary intensity and in a constant crossed field are obtained. The behavior of the cross section of the process as a function of the particle energies and the external field intensity is investigated for various values of the Higgs boson mass. It is shown that there is a logarithmic increase in the photoproduction cross section at superhigh energies up to a value significantly exceeding the cross section of the reaction e ++e Z+H, which is presently regarded as the most probable channel for the production of Higgs bosons.

Using the minimal extension of the standardmodel which allows for charged scalar bosons in the model we compute the total cross section for the production of these charged scalar bosons at HERA. The production rates are found to be small.  相似文献

A system of three charged bosons confined in a two-dimension harmonic trap has been investigated. We report a calculation for the energy spectrum of the low-lying states of a system of three charged bosons. The important feature of the low-lying states of three charged bosons in two-dimension space is obtained via an analysis the energy spectrum.  相似文献

We describe methods which can be used to search for pair-produced charged Higgs bosons in e+e? collisions. These methods use a jet identification procedure previously developed by the authors. The results of tests on simulated data are presented. We include a study of effects of QCD backgrounds and a crude estimation of the effects of experimental errors.  相似文献
