Measurement of theZZproduction cross section using the full CDF II data set

Abstract

We present a measurement of the ZZ-boson pair-production cross section in 1.96 TeV center-of-mass energy pp collisions. We reconstruct final states incorporating four charged leptons or two charged leptons and two neutrinos from the full data set collected by the Collider Detector experiment at the Fermilab Tevatron, corresponding to 9.7 fb −1 of integrated luminosity. Combining the results obtained from each final state, we measure a cross section of 1.04 þ0.32 −0.25 pb, in good agreement with the standard model prediction at next-to-leading order in the strong-interaction coupling.

Anomalous triple-gauge-boson interactions in vector-boson pair production with Recola2

“…The production of leptonically decaying electroweak boson pairs has been intensively studied at the Tevatron [1][2][3][4][5] and in Run I of the LHC [6][7][8][9][10][11][12], searching for deviations from the SM predictions and setting limits on the strength of possible non-SM triple-gauge-boson interactions (anomalous triple-gauge-boson couplings, aTGCs in the following). Recently, the first results for WW, ZZ and WZ production at 13 TeV have been presented in Refs.…”

Effect of flavor-dependent partonic transverse momentum on the determination of the W boson mass in hadronic collisions

“…Precise determinations of M W have been extracted from pp collisions at D0 [21] and at CDF [22], and from pp collisions at ATLAS [23] with a total uncertainty of 23 MeV, 19 MeV and 19 MeV, respectively. The current world average, based on these measurements and the ones performed at LEP, is M W =80.379±0.012 GeV [24].…”

“…Then, assuming the parameters to be flavor independent, they use these estimates to predict the q W T distribution. The uncertainty on M W due to the modelling of q W T via template fits for the distributions in (m T , p T , p T ν ) are, respectively, δM W = (3,9,4) MeV for CDF [22], δM W = (2,5,2) MeV for D0 [21] and δM W = (3,3) MeV for ATLAS [23] (the ATLAS analysis did not include p T ν in the template fit).…”

“…For proton-proton collisions at √ s = 7 TeV, we generate pseudodata for the q T distribution of the Z boson (22 bins similar to the ATLAS ones [23]) using the flavor-independent set in the DYqT code at O(α s ) and NLL accuracy. We do the same for proton-antiproton collisions at √ s = 1.96 TeV (72 bins similar to the CDF ones [22]). We assign to each of the q T bins an uncertainty equal to the experimental one.…”

Sensitivity on anomalous neutral triple gauge couplings via ZZ production at FCC-hh

“…The production of ZZ dibosons in the 4 final state * aliyilmaz@giresun.edu.tr † senol a@ibu.edu.tr ‡ denizli h@ibu.edu.tr § ilkay.turk.cakir@cern.ch ¶ ocakir@science.ankara.edu.tr have been studied by various collaborations such as the Large Electron-Positron (LEP) [3][4][5][6][7][8] where the first bounds on anomalous neutral triple gauge couplings (aNTGCs) using e + e − collider was obtained, the Collider Detector at Fermilab (CDF) [9,10] and DØ [11,12] also searched the limits of aNTGC at Tevatron pp collider. Recently, ATLAS [13,14] and CMS [15,16] collaborations published the improved limits of aNTGCs thanks to the center of mass energy of LHC in the range of 13 TeV at the LHC.…”
