Resolution of the Rb − αs crisis of the SM in an exotic ETC scenario.
نویسنده
چکیده
In this article we show that the Rb−αs crisis of the SM can be resolved in a commuting TC scenario with sideways gauge bosons only if the ETC representation contains mirror technifermions. For a toy ETC model we estimate the value of ξ t = gE,L/g U E,R that is needed to produce the observed LEP excess in Rb. It is also shown that the same value of ξ t resolvs the αs crisis of the SM but produces a δρnew which is barely within the present experimental bound.

Implications of Precision Electroweak Data
There are two aspects to the 1995 summer update of the combined preliminary electroweak data from LEP and SLC. On the one hand, agreement between experiments and the Standard Model (SM) has improved for the line-shape and the asymmetry data. The τ widths and asymmetries are now consistent with e– μ–τ universality, and all the asymmetry data including the left-right asymmetry from SLC are consis...
متن کاملMATCHING THE LOW AND HIGH ENERGY DETERMINATIONS OF αs(MZ) IN THE MSSM
Recent calculations of supersymmetric corrections to the conflicting ratios Rb and Rc have shown that an alleged discrepancy between the SM predictions of these observables and the corresponding experimental values can be cured in the MSSM within a certain region of the parameter space. Here we show that, in this very same region, also a well-known discrepancy between the low and high energy de...
متن کاملLooking Beyond the Standard Model through Precision Electroweak Physics
The most important hint of physics beyond the Standard Model (SM) from the 1995 precision electroweak data is that the most precisely measured quantities, the total, leptonic and hadronic decay widths of the Z and the effective weak mixing angle, sin θW , measured at LEP and SLC, and the quark-lepton universality of the weak charged currents measured at low energies, all agree with the predicti...
متن کاملTHE QUANTUM CORRELATION Rb-Rc IN THE MSSM: MORE HINTS OF SUPERSYMMETRY?
We study the correlation of quantum effects on the ratiosRb and Rc within the framework of the MSSM. While in the SM the quantity Rb is in discrepancy with experiment at the 2 σ level from below, and Rc differs from the experimental result at the 1.5 σ level from above, the theoretical prediction for both observables could simultaneously improve in the MSSM, provided that tan β is large enough ...
متن کاملALEPH Four - Jet Excess , R b and R − Parity Violation ∗
We review briefly the indications for some relatively light superpartners based on the Rb anomaly and discuss the dependence of the potential increase in Rb on the assumption about R−parity (non)conservation. We point out that the exotic 4-jet events reported by ALEPH may constitute a signal for supersymmetry with such a light spectrum and with explicitly broken R−parity. A parton level simulat...
