We study the single production of fourth-family quarks through the process pp→Q′jX at the Large Hadron Collider (LHC). We have calculated the decay widths and branching ratios of the fourth-family quarks
(b′ and t′) in the mass range 300–800 GeV. The cross sections for the signal and background processes have been calculated in a Monte
Carlo framework. It is shown that the LHC can discover single t′ and b′ quarks if the CKM matrix elements |V

The ArgoNeuT Collaboration presents the first measurements of inclusive muon neutrino charged current differential cross sections on argon. Obtained in the NuMI neutrino beam line at Fermilab, the flux-integrated results are reported in terms of outgoing muon angle and momentum. The data are consistent with the Monte Carlo expectation across the full range of kinematics sampled, 0°<θ(μ)<36° and 0

We have studied the Rashba spin–orbital effect on a diluted magnetic semiconductor (DMS) cylinder surface in the presence of a magnetic field parallel to the cylinder axis, taking into account the Zeeman coupling and the s–d exchange interaction between the carriers and the magnetic ions. We have obtained an analytical expression for the electron energy spectrum, which depends on the magnetic ion concentration, temperature and strength of magnetic field. The results are used to obtain the conductance of the cylinder at finite temperature. It is shown that the presence of additional local extremum points in the subbands of the electronic spectrum leads to a nonmonotonic dependence of the ballistic conductance of the system on the chemical potential and magnetic field. In the presence of anomalous Zeeman terms with taking into account the Rashba splitting, each minimum of subband contributes G0/2 to conductance and each local maxima in the subband, actually reduce the conductance by G0/2 compared with the value G0, without the anomalous Zeeman splitting. The effect of finite temperature on the DMS cylinder conductance is a smearing out the sharp steps in the zero-temperature conductance, and shifting the peaks due to the temperature dependence of the s–d exchange interaction term. 相似文献

We consider pair production of new down-type isosinglet quarks originating from E6, which is the favorite gauge symmetry group in superstring inspired GUT models. The study concentrates on the possibility
of observing the pair production of the lightest of the new quarks, D, in the ATLAS detector at the forthcoming LHC accelerator,
in the channel DD̄→ZjZj . Both signal and background events are studied using tree level event generators based on Monte Carlo
techniques. The detector effects are taken into account using the ATLAS fast simulation tool. It is shown that ATLAS can observe
the D quark within the first year of low luminosity LHC operation if its mass is less than 650 GeV. For the case of two years
of full luminosity running, 1 TeV can be reached with about three sigma significance. 相似文献

We evaluate the discovery reach of the ATLAS experiment for down type isosinglet quarks, D, using both their neutral and charged
decay channels, namely the process pp→DD̄+X with subsequent decays resulting in 2ℓ+2j+≠ET, 3ℓ+2j+≠ET and 2ℓ+4j final states. The integrated luminosity required for observation of a heavy quark is estimated for a mass range
between 600 and 1000 GeV using the combination of results from different search channels. 相似文献
