Searching for Charged Higgs Boson in Polarized Top Quark

open access: yes, 2013
The charged Higgs boson is quite common in many new physics models. In this study we examine the potential of observing a heavy charged Higgs boson in its decay mode of top-quark and bottom-quark in the Type-II Two-Higgs-Doublet-Model. In this model, the

Model-independent constraints on the CKM matrix elements |V tb |, |V ts | and |V td |

open access: yesJournal of High Energy Physics, 2019
Single top quark production cross sections at hadron colliders are traditionally used to extract the modulus of the V tb element of the Cabibbo-Kobayashi-Maskawa matrix under the following assumption: |V tb | ≫ |V td |, |V ts |.

Top physics with 0.70-1.08/fb of pp collisions with the ATLAS detector at the LHC

open access: yes, 2011
With data collected during the first half of 2011 pp run of the Large Hadron Collider at \surds = 7 TeV, a substantial data sample of high p_T triggers, 1.08/fb, has been collected by the ATLAS detector.

Quantum tops at circular lepton colliders

open access: yesJournal of High Energy Physics
We study the quantum properties of top quark pairs in lepton colliders with unpolarised beams, including spin correlations, entanglement, and violation of Bell inequalities.

Measurements of top quark properties at the Tevatron collider

open access: yes, 2011
The discovery of the top quark in 1995 opened a whole new sector of investigation of the Standard Model; today top quark physics remains a key priority of the Tevatron program.

Search for electroweak production of a vector-like quark decaying to a top quark and a Higgs boson using boosted topologies in fully hadronic final states

open access: yesJournal of High Energy Physics, 2017
A search is performed for electroweak production of a vector-like top quark partner T of charge 2/3 in association with a standard model top or bottom quark, using 2.3 fb−1 of proton-proton collision data at s = 13 $$ \sqrt{s}=13 $$ TeV collected by the ...

Invariant-mass threshold resummation for the production of four top quarks at the LHC

open access: yesJournal of High Energy Physics
Using invariant-mass threshold resummation, we compute the invariant-mass distribution and the total cross section for t t ¯ t t ¯ $$ t\overline{t}t\overline{t} $$ production at the LHC with centre-of-mass energy of 13.6 TeV at NLL′ accuracy.
