چکیده

We present a measurement of the W-boson mass using 200 pb{-1} of data collected in pp[over ] collisions at sqrt[s]=1.96 TeV by the CDF II detector at run II of the Fermilab Tevatron. With a sample of 63 964 W-->enu candidates and 51 128 W-->munu candidates, we measure M_{W}=80 413+/-34{stat}+/-34{syst}=80,413+/-48 MeV/c;{2}. This is the most precise single measurement of the W-boson mass to date.

Update of the Combination of CDF and D 0 Results for the Mass of the W Boson The Tevatron Electroweak Working Group ∗ for the CDF and D 0 Collaborations

We summarize and combine the results on the direct measurements of the mass of the W boson in data collected by the Tevatron experiments CDF and D0 at Fermilab. Earlier of Run-II data are now combined with two new, high statistics Run-II measurements: a CDF measurement in both electron and muon channels using 2.2 fb −1 of integrated luminosity collected between 2002 and 2007, and a D0 measureme...

تولید مزون‌های سنگین (S1)Bc در LHC و Tevatron Run II با در نظر گرفتن اسپین کوارک

 In this research, we have investigated the effect of spin orientation of quarks on the production of the Bc(1S) heavy mesons. We have calculated the fragmentation functions at initial scale µ° .Then we have modified to µ these fragmentation functions by using Altrali-Parisi equation. Also, we have calculated the transverse momentum distributions of the differential cross sections . Our results...

Searches and Prospects for the Standard Model Higgs Boson at the Tevatron

The Higgs boson is the only elementary scalar particle expected in the standard model (SM). Its discovery would be a major success for the SM and would provide new experimental insights into the electroweak symmetry breaking mechanism. Direct measurements at LEP have excluded a SM Higgs boson with a mass mH < 114.4 GeV at 95% C.L. but constraints from precision measurements nevertheless favor a...
