Optimal Spin Basis in Polarized Photon Linear Colliders [PDF]

open access: yes, 1997
We analyze the spin correlations of the top quark pairs produced at Photon Linear Colliders. We employ the circular polarized photon beams and general spin basis for the top quark pair.

Differential top-quark pair production measurements

open access: yesEPJ Web of Conferences, 2014
The large number of top quarks produced at the CERN Large Hadron Collider makes it possible to measure the top-quark pair production cross-section differentially with respect to different observables. Differential measurements are important for precision

Constraining top-quark couplings combining top-quark and $$\varvec{B}$$ B decay observables

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We present a first, consistent combination of measurements from top-quark and B physics to constrain top-quark properties within the Standard Model Effective Field Theory (SMEFT).

Top quarks and flavor physics [PDF]

open access: yesPhysical Review D, 1995
Because of the top quark's very large mass, about 175~GeV, it now provides the best window into flavor physics. Thus, pair--production of top quarks at the Tevatron Collider is the best probe of this physics until the Large Hadron Collider turns on in the next century.

Search for W′ bosons decaying to a top and a bottom quark at s=13TeV in the hadronic final state

open access: yesPhysics Letters B, 2021
A search is performed for W′ bosons decaying to a top and a bottom quark in the all-hadronic final state, in proton-proton collisions at a center-of-mass energy of 13TeV.

Collider sensitivity to SMEFT heavy-quark operators at one-loop in top-quark processes

open access: yesJournal of High Energy Physics
We study the effects of four-heavy-quark operators in the production of top quarks in the framework of the Standard Model Effective Field Theory (SMEFT) at the LHC. In particular, we compute for the first time the total contribution of the four-top-quark
