BB interactions with static bottom quarks from Lattice QCD [PDF]

open access: yes, 2015
The isospin, spin and parity dependent potential of a pair of B mesons is computed using Wilson twisted mass lattice QCD with two flavours of degenerate dynamical quarks. The B meson is addressed in the static-light approximation, i.e.

Plate tectonics in the microscopy realm: Molecular insights into morphological variability of Peridinium willei (Peridiniales, Dinophyceae)

open access: yesTAXON, EarlyView.
Abstract Freshwater Peridinium willei (Peridiniaceae) is globally distributed, but reports linking its morphologies with DNA sequence data remain scarce. The taxonomy of the species, and its infraspecific taxa, remain ambiguous due to the lack of DNA sequence data for the original and type material.

Search for vector-like T and B quark pairs in final states with leptons at s=13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search is presented for pair production of heavy vector-like T and B quarks in proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV. The data sample corresponds to an integrated luminosity of 35.9 fb−1, collected with the CMS detector at the CERN LHC

Local spin alignment of vector mesons in relativistic heavy-ion collisions

open access: yesPhysics Letters B, 2021
We investigate the spin alignment of vector mesons arising from locally polarized quarks and anti-quarks (local spin alignment) in heavy-ion collisions.

Heavy and light quarks in the instanton vacuum

open access: yesEPJ Web of Conferences, 2012
Assuming the gluon field is well approximated by instanton configurations we derive a light quarks determinant and calculate its contribution to the specific heavy quarks correlators – namely, the heavy quark propagator and heavy quark-aniquark ...

Disproportional ventilatory response to incremental exercise in individuals with cerebral palsy

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
Individuals with cerebral palsy demonstrate a disproportionate ventilatory response during incremental exercise. Compared with typically developing peers, respiratory frequency increases earlier and at comparable exercise intensities, contributing to higher perceived exertion and reduced ventilatory efficiency. At task failure, respiratory frequency is

Constraints on the quark mixing matrix with vector-like quarks

open access: yesNuclear Physics B, 2020
While a chiral fourth generation of quarks is almost ruled out from the data on Higgs boson production and decay at the Large Hadron Collider, vector-like quarks are still a feasible option to extend the fermionic sector of the Standard Model.

Dark Matter Searches with Top Quarks

open access: yesUniverse, 2022
Collider signatures with top quarks provide sensitive probes of dark matter (DM) production at the Large Hadron Collider (LHC). In this article, we review the results of DM searches in final states with top quarks conducted by the ATLAS and CMS ...
