MEMORIES OF MURRAY AND THE QUARK MODEL [PDF]
Life at Caltech with Murray Gell-Mann in the early 1960's is remembered. Our different paths to quarks, leading to different views of their reality, are described.

Probing top quark neutral couplings in the Standard Model Effective Field Theory at NLO in QCD [PDF]
A bstractTop quark pair production in association with a Z-boson or a photon at the LHC directly probes neutral top-quark couplings. We present predictions for these two processes in the Standard Model (SM) Effective Field Theory (EFT) at next-to-leading

Radioactivity of quark nuggets
Quark nuggets Q Z A $$ {}_{\textrm{Z}}{}^{\textrm{A}}\textrm{Q} $$ , as Fermionic non-topological solitons, could have their mass per baryon smaller than ordinary nuclei and behave as exotic nuclei with different relations of atomic number and atomic ...

Molecular components in D*s0(2317) and Ds1(2460) mesons
Different experiments have confirmed that the D*s0(2317) and Ds1(2460) mesons are very narrow states located, respectively, below the DK and D*K thresholds. This is markedly in contrast with the expectations of naive quark models and heavy quark symmetry.

Thermo-magnetic effects in quark matter: Nambu-Jona-Lasinio model constrained by lattice QCD [PDF]
.The phenomenon of inverse magnetic catalysis of chiral symmetry in QCD predicted by lattice simulations can be reproduced within the Nambu-Jona-Lasinio model if the coupling G of the model decreases with the strength B of the magnetic field and ...

Acute ketone monoester ingestion lowers resting cerebral blood flow: a randomized cross‐over trial
Abstract figure legend This double‐blind, placebo‐controlled, randomized cross‐over trial investigated the effects of ketone monoester (KME) ingestion on resting cerebral blood flow (CBF) in young adults. We demonstrate that KME supplementation lowers CBF in a dose‐dependent manner over 2‐houra post‐ingestion, whereas CBF remained unchanged following ...

Top quark measurements in the CMS experiment
Experimental results on top-quark physics obtained at the CMS experiment are reported based on the data recorded at centre-of-mass energy up to 13 TeV. Inclusive and differential cross sections for both top-quark pair and single top-quark production are ...

Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...

ABSTRACT Rituals and routines are used to define autism. However, descriptions that come from diagnostic manuals exclude many people from being recognised as autistic initially, and exclude others from owning a positive autistic identity. Different examples and descriptions of these behaviours are missing from clinical guidelines.

A general Lorentz-covariant quark model of mesons, whose nonrelativistic limit corresponds to Isgur-Scora-Grinstein-Wise model, is constructed. It possesses the heavy quark symmetry and can be easily applied to calculation of form factors. Besides it can be engaged in novel tasks, such a the investigation of the two photon decay of scalar mesons.
