A2:θH=0.0737,mKK=10.3TeV→mZ1=8.52TeV, whereZ1is the first KKZboson. The masses of the first KKγandZRbosons are similar to those of the first KKZboson. The parameters are chosen such that the couplings of the SM-likeZboson to fermions (other than the top quark) agree with current ...
What is an antiproton made of? Antiproton. The proton is made up of two up quarks and one down quark. The electrical charge of the proton is then: (+2/3) + (+2/3) + (-1/3) = (+1). The antiproton is made up oftwo up antiquarks and one down antiquark. ...
1 Introduction Two decades after the discovery of the top quark [1,2], many of its properties are still to be determined or are only loosely constrained by experimental data. Among these prop- erties are the couplings between the top quark and the vector bosons. The existence of non-zero...
Matter is a physical substance that has a mass and takes up a volume. It is made up of small entities that are known as particles. The three most frequently encountered particles are protons, neutrons, and electrons.Answer and Explanation: ...
1 Introduction Hadrons can be classified either as mesons made of a pair of quark and antiquark or as baryons made of three quarks in the conventional quark model, which has been rather suc- cessful at least up to 2003. According to the quark model [1], a e-mail: lisheng.geng@...
The symbol W (mi | mt) in eq. (6.4) represents the probabilities for the wrong jet combinations, which are parametrized using analytic functions fitted to the mass distribution of jet combinations from simulated tt events known to have wrong jet-to-quark assignments. The probability for tt ...
working always to linear order in [Math Processing Error]λGB for simplicity (hence all the formulas containing [Math Processing Error]λGB below are valid up to [Math Processing Error]O(λGB2) corrections, although we choose not to unnecessarily repeat this symbol in each and every expression...
The symbol φ denotes the azimuthal angle of the lepton or missing transverse momentum vector. –5– • A parton-level top-quark is the MC generator-level top-quark selected before it decays but after any radiative emissions;4 • A particle-level pseudo-top-quark (hadronic and leptonic) ...
