A sequential fourth generation of quarks and leptons is allowed by precision electroweak constraints if the mass splitting between the heavy quarks is between 50 and 80 GeV. Although heavy quarks can be easily detected at the LHC, it is very difficult to detect a sequential heavy charged lepton, L, due to large backgrounds. Should the L mass be above 250 GeV, it cannot be pair-produced at a 500 GeV ILC. We calculate the cross section for the one-loop process e(+)e(-)-> L tau. Although the cross section is small, it may be detectable. We also consider contributions from the two-Higgs doublet model and the Randall-Sundrum model, in which case the cross section can be substantially higher.

Measurement of the t(t)over-bar production cross section in the e mu channel in proton-proton collisions at root s=7 and 8 TeV
Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2016-08-01)
The inclusive cross section for top quark pair production is measured in proton-proton collisions at root s = 7 and 8TeV, corresponding to 5.0 and 19.7 fb(-1), respectively, with the CMS experiment at the LHC. The cross sections are measured in the electron-muon channel using a binned likelihood fit to multi-differential final state distributions related to identified b quark jets and other jets in the event. The measured cross section values are 173.6 +/- 2.1 (stat)(-4.0)(+ 4.5)(syst) +/- 3.8 (lumi) pb at ...
Investigations of spinodal dynamics in asymmetric nuclear matter within a stochastic relativistic model
Yılmaz, Osman; ACAR, FERİDE PINAR; Saatci, S.; GÖKALP, AHMET (Springer Science and Business Media LLC, 2013-03-01)
Early development of spinodal instabilities and density correlation functions in asymmetric nuclear matter are investigated in the stochastic extension of the Walecka-type relativistic mean field including coupling with rho meson. Calculations are performed under typical conditions encountered in heavy-ion collisions and in the crusts of neutron stars. In general, growth of instabilities occur relatively slower for increasing charge asymmetry of matter. At higher densities around rho = 0.4 rho(0) fluctuatio...
Measurement of the charge asymmetry in top-quark pair production in proton-proton collisions at root s=7 TeV
Chatrchyan, S.; et. al. (Elsevier BV, 2012-03-01)
The difference in angular distributions between top quarks and antiquarks, commonly referred to as the charge asymmetry, is measured in pp collisions at the LHC with the CMS experiment. The. data sample corresponds to an integrated luminosity of 1.09 fb(-1) at a centre-of-mass energy of 7 TeV. Top-quark pairs are selected in the final state with an electron or muon and four or more jets. At least one jet is identified as originating from b-quark hadronization. The charge asymmetry is measured in two variabl...
Measurement of the mass difference between top and antitop quarks
Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-06-01)
A measurement of the mass difference between the top and the antitop quark (Delta m(t) = m(t) - m((t) over bar)) is performed using events with a muon or an electron and at least four jets in the final state. The analysis is based on data collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 4.96 +/- 0.11 fb(-1), and yields the value of Delta m(t) = -0.44 +/- 0.46 (stat.) +/- 0.27 (syst.) GeV. This result is consistent with equality of particle and antiparticle masses requ...
Measurement of the differential cross-sections of inclusive, prompt and non-prompt J/psi production in proton-proton collisions at root s=7 TeV
Aad, G.; et. al. (Elsevier BV, 2011-09-21)
The inclusive production cross-section and fraction of mesons produced in B-hadron decays are measured in proton–proton collisions at with the ATLAS detector at the LHC, as a function of the transverse momentum and rapidity of the , using 2.3 pb−1 of integrated luminosity. The cross-section is measured from a minimum of 1 GeV to a maximum of 70 GeV and for rapidities within giving the widest reach of any measurement of production to date. The differential production cross-sections of prompt and non-pr...
