Final State Interactions

Dalitz analyses are introduced as the method for studying hadronic decays. An accurate description of hadron final states is critical not only to an understanding of the strong coupling regime of QCD, but also to the precision extraction of CKM matrix elements. The relation of such final state interactions to scattering processes is discussed.

Parton Distribution Functions

We present the most recent precision electroweak measurements of single W and Z boson cross section and properties from the LHC and Tevatron colliders, analyzing data collected by ATLAS, CDF, CMS, D0, and LHCb detectors. The results include the measurement of the single W and Z boson cross section at LHC, the differential cross section measurements, the measurement of W boson mass, the measurement of W and Z charge asymmetry. These measurements provide precision tests on the electroweak theory, high order predictions and the information can be used to constraint parton distribution functions.

Dielectron Channel

We present results on the searches for Extra Dimensions and Z′ Bosons conducted at the Tevatron's DØ Detector using dielectron, diphoton, and dimuon final states. The theoretical frameworks of Large Extra Dimensions (LED), Randall-Sundrum Extra Dimensions (RS), TeV-1 Extra Dimensions, and Z′ bosons are explored in the dielectron and diphoton channels, while LED and Z′ bosons are also searched for in the dimuon final state. In the absence of signals we find lower 95% confidence level (CL) limits on the mass of a SM-like Z′ boson of 780 GeV and 680 GeV in the dielectron and dimuon channels, respectively. Furthermore, we find a lower 95% CL limit of 1.12 TeV on the TeV-1 compactification scale ( M C) in the dielectron channel. In the diEM channel and LED framework we set a lower 95% CL limit of 1.43 TeV (GRW) on the fundamental Planck scale ( M S). Using a dimuon final state we find a lower 95% CL limit of 1.1 TeV (GRW) on M S. We also find a lower 95% CL mass limit of 785 GeV on a RS graviton decaying into a dielectron or diphoton final state.
