Initial–final-state interference in the Z line-shape

Initial–Final-State Interference in the Z line-shape

The uncertainty in the determination of the Z line-shape parameters coming from the precision of the calculation of the Initial-State Radiation and Initial–Final-State Interference is 2×10−4 for the total cross section σ0 had at the Z peak, 0.15 MeV for the Z mass MZ , and 0.1 MeV for the Z width ΓZ . Corrections to Initial–Final-State Interference beyond O(α1) are discussed. Submitted to Physi...

The line shape of the Z boson 1 Tord Riemann

At LEP 1, cross sections and cross section asymmetries may be analysed model independently. Cross sections depend on four, asymmetries on two free parameters. As an example, I discuss the model independent Z boson mass determination from the Z line shape and compare it to the Standard Model approach.

Gaussian Z Channel with Intersymbol Interference

In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...

MIMO Z Channel Interference Management

MIMO Z Channel is investigated in this paper. We focus on how to tackle the interference when different users try to send their codewords to their corresponding receivers while only one user will cause interference to the other. We assume there are two transmitters and two receivers each with two antennas. We propose a strategy to remove the interference while allowing different users transmit ...
