Article Synopsis
  • - The study investigates the strange quark content of protons by measuring the production cross section of W bosons and charm quarks in proton-proton collisions at 13 TeV, using data from the CMS detector at the LHC.
  • - W bosons are identified through their decays into leptons (electrons or muons) and neutrinos, while charm quarks are tagged by detecting muons or secondary vertices in jets.
  • - The measurements, which reach a precision of 1%, include both inclusive and differential analyses based on the transverse momentum and pseudorapidity of the leptons, and the results are compared with advanced theoretical predictions in quantum chromodynamics.

Private, subjective beliefs about uncertainty have been found to have idiosyncratic computational and neural substrates yet, humans share such beliefs seamlessly and cooperate successfully. Bringing together decision making under uncertainty and interpersonal alignment in communication, in a discovery plus pre-registered replication design, we examined the neuro-computational basis of the relationship between privately held and socially shared uncertainty. Examining confidence-speed-accuracy trade-off in uncertainty-ridden perceptual decisions under social vs isolated context, we found that shared (i.
