Investigation of quark–antiquark interaction properties using leading particle measurements in e+e annihilationFragmentationFormation timeQuark massesStrong interaction potentialMeasurements of heavy quark production in electron-positron collisions are used to analyse the strong interactions between quarks and ...
Quantum chromodynamics, the theory of the strong force, describes interactions of coloured quarks and gluons and the formation of hadronic matter. Conventional hadronic matter consists of baryons and mesons made of three quarks and quark-antiquark pairs, respectively. Particles with an alternative quark...

Search for second generation leptoquarks in the dimuon plus dijet channel of p-pbar collisions at sqrt{s}=1.8 TeV We report on a search for second generation leptoquarks (ensuremath{Phi}2) using a data sample corresponding to an integrated luminosity of 110 pb -1 collected at the Collider...
We also note the stronger relations that come from specializing in various ways, including antiquark and strange quark suppression, and the dual valence plus sea model. Finally we construct illustrative parametrizations, fitted to the electron data and minimizing the antiquark momentum content, in ...
Search for resonant top quark plus jet production in tt +jets events with the ATLAS detector in pp collisions at √s=7 TeV This paper presents a search for a new heavy particle produced in association with a top or antitop quark. Two models in which the new heavy particle is a ... ...
Quark nuggets are theoretical objects composed of approximately equal numbers of up, down, and strange quarks and are also called strangelets and nuclearites. They have been proposed as a candidate for dark matter, which constitutes ~85% of the universe
I Bigi - 《Annual Review of Nuclear & Particle Science》 被引量: 25发表: 1997年 Electromagnetic mass splitting of hadrons in the quark model Assuming that electromagnetic interactions between quarks are Coulomb plus magnetic-moment interactions, we derive an equality and several inequalities among th...
The nucleon spin structure in terms of its parton constituents is a fundamental question in QCD. The sea quark contribution to the nucleon spin is an important piece for a complete understanding of the nucleon spin structure. The producti
