Model Independent Determination of the Top Yukawa Coupling from LHC and LC

چکیده
We show how a measurement of the process pp → tt̄H +X at the LHC and a measurement of the Higgs boson branching ratios BR(H → bb̄) and BR(H → WW) at a future linear electron positron collider can be combined to extract amodel-independent measurement of the top quark Yukawa coupling. We find that for 120 GeV < mH < 200 GeV a measurement precision of 15% including systematic uncertainties can be achieved for integrated luminosities of 300 fbat the LHC and 500 fbat the LC at centre-of-mass energy of 350 GeV.

In this research we study the Mono-Z signature along with dark matter production at the LHC in a renormalizable dark matter model. We look at processes with L+L-+MET in the final state. We simulate signal and background events at central mass energy 14 TeV We then evaluate the LHC sensitivities for some points in the model parameter space for two integrated luminosities L=100 fb-1 and L=1 ab-1 ...
متن کاملThe massive Elko spinor field in the de Sitter braneworld model
The Elko spinor field is a spin 1/2 fermionic quantum field with a mass dimension introduced as a candidate of dark matter. In this work, we study the localization of Elko fields on a de Sitter thick brane constructed by a canonical or phantom scalar field. By presenting the mass-independent potentials of Kaluza-Klein (KK) modes in the corresponding Schrödinger equations, it is shown that the E...
متن کاملLeading Yukawa corrections to Higgs production associated with a tagged bottom anti-bottom pair in the Standard Model at the LHC
Considering the large value of the top Yukawa coupling, we investigate the leading one-loop Yukawa electroweak corrections that can be induced by the top quark in a process such as Higgs production in association with a tagged bottom anti-bottom pair at the LHC. At NLO these contributions are found to be small at the LHC both for the total cross section and for the distributions. In the limit o...
متن کاملMeasuring the top-quark Yukawa coupling at hadron colliders via tt̄h, h → W+W−
We study the signal and background for the process tt̄h, h → WW at the LHC and a 100 TeV VLHC. Signals are studied in two-, three-, and four-lepton final states. We find a statistical uncertainty in the top-quark Yukawa coupling at the LHC of 16%, 8%, 12% for mh = 130, 160, 190 GeV, respectively. The statistical uncertainty at the VLHC is likely to be negligible in comparison with the systematic...
متن کاملProbing Higgs Bosons with Large Bottom Yukawa Coupling at Hadron Colliders
The small mass of the bottom quark, relative to its weak isospin partner, the top quark, makes the bottom an effective probe of new physics in Higgs and top sectors. We study the Higgs boson production associated with bottom quarks, pp̄/pp → φbb̄ → bb̄bb̄, at the Fermilab Tevatron and the CERN LHC. We find that strong and model-independent constraints on the size of the φ-b-b̄ coupling can be obtain...
