Vector-like singlet quarks: A roadmap [PDF]

open access: yesPhysics reports, 2023
We review the theory and phenomenology of isosinglet vector-like quarks (VLQs). In recent years, interest in VLQs has been increasing, due to their contributions to new physics effects that can be tested in experiments at LHC and High-Luminosity LHC. The

Quantum Discord and Steering in Top Quarks at the LHC. [PDF]

open access: yesPhysical Review Letters, 2022
Top quarks have been recently shown to be a promising system to study quantum information at the highest-energy scale available. The current lines of research mostly discuss topics such as entanglement, Bell nonlocality or quantum tomography.

Entanglement and quantum tomography with top quarks at the LHC [PDF]

open access: yesThe European Physical Journal Plus, 2020
Entanglement is a central subject in quantum mechanics. Due to its genuine relativistic behavior and fundamental nature, high-energy colliders are attractive systems for the experimental study of fundamental aspects of quantum mechanics.

From hadrons to quarks in neutron stars: a review [PDF]

open access: yesReports on progress in physics. Physical Society, 2017
In recent years our understanding of neutron stars has advanced remarkably, thanks to research converging from many directions. The importance of understanding neutron star behavior and structure has been underlined by the recent direct detection of ...

Quark-quark interaction and quark matter in neutron stars [PDF]

open access: yesPhysical Review C, 2022
Hyperon ($Y$) mixing in neutron-star matter brings about a remarkable softening of the equation of state (EoS) and the maximum mass is reduced to a value far less than $2M_{\odot}$. One idea to avoid this "hyperon puzzle in neutron stars" is to assume that the many-body repulsions work universally for every kind of baryons.

Heavy quarks embedded in glasma [PDF]

open access: yes, 2020
Heavy quarks, which are produced at the earliest stage of relativistic heavy-ion collisions, probe the entire history of the quark-gluon plasma that is created in the collision.

CP violation of quarks in A4 modular invariance [PDF]

open access: yesPhysics Letters B, 2018
We discuss the quark mass matrices in the A 4 modular symmetry, where the A 4 triplet of Higgs is introduced for each up-quark and down-quark sectors, respectively. The model has six real parameters and two complex parameters in addition to the modulus τ

Search for pair production of vector-like quarks in the fully hadronic final state [PDF]

open access: yes, 2019
The results of two searches for pair production of vector-like T or B quarks in fully hadronic final states are presented, using data from the CMS experiment at a center-of-mass energy of 13 TeV.
