محاسبه اثر نوترینو در محاسبه ساختار ستاره نوترونی تازه متولد شده
In this paper, we consider the first case of formation of newborn neutron star named protoneutron star which is described with constant entropy per baryon about 1-2kB ( kB is Boltzman constant ) and lepton fraction about 0.3-0.4. In this case, by considering the neutrinos mean energy in our calculations, we compute the total energy, equation of state, mass and radius of protoneutron star. Fin...
متن کاملPrecise measurements of the top mass and direct measurement of the mass difference between top and antitop quarks at DØ
We report on measurements of the mass using dilepton and lepton+jet data collected with the D0 detector. These results are compared to the top mass extracted from the t ¯ t cross section using higher-order quantum chromodynamics calculations. We also present a direct measurement of the mass difference between top and antitop quarks (∆m) in lepton+jets t ¯ t final states using the " matrix eleme...
متن کاملCombined template-based Top Quark Mass Measurement in the Lepton+Jets and Dileptons Channels Using 4.8 fb−1 of data
We report on a simultaneous measurement of the top quark mass (Mtop) in the Lepton+Jets and Dilepton channels using pp̄ collisions at √ s = 1.96 TeV from 4.8 fb −1 of data collected with the CDF detector at the Fermilab Tevatron. In the Lepton+Jets channel, a top quark mass (m t ) is reconstructed for every event by minimizing a χ-like function to the overconstrained kinematics of the tt̄ system....
متن کاملPrecision Higgs boson mass determination at lepton colliders
We demonstrate that a measurement of the Bjorken process e + e − , µ + µ − → ZH in the threshold region can yield a precise determination of the Higgs boson mass. With an integrated luminosity of 100 fb −1 , it is possible to measure the Higgs mass to within 60 MeV (100 MeV) for m H = 100 GeV (150 GeV). One of the triumphs of the LEP program was the measurement of the Z-boson mass to two MeV. E...

Top quark mass determination near tt̄ threshold at lepton colliders ∗
Top quark mass determination near t ¯ t threshold at lepton colliders * Abstract Future e + e − linear colliders will enable us to determine the top quark mass with high accuracy from the measurement of the 1S peak position of (remnant of) toponium. The estimated statistical error in this measurement is about 50 MeV with integrated luminosity of 30 fb −1. We calculate O(α 5 s m) corrections to ...
