Today, at the Moriond conference, the ATLAS and CMS collaborations have both presented the observation of a very rare process: the simultaneous production of four top quarks. They were observed using ...
Unlike electrons, quarks cannot wander freely in ordinary matter. They are confined by the strong force within hadrons such as the protons and neutrons that make up atomic nuclei. However, at very hig...
Kantian Causality and Quantum Quarks:The Compatibility between Quantum Mechanics and Kant’s Phenomenal World
Kant quantum theory Copenhagen interpretation indeterminism perspectives law of causality transcendental idealism teoría cuantica interpretación de Copenhague indeterminismo perspectivas ley de causalidad idealismo trascendental

Quantum indeterminism seems incompatible with Kant’s defense of causality in his Second Analogy.The Copenhagen interpretation also takes quantum theory as evidence for anti-realism. This article argue...
Final state interactions in the decay of heavy quarks
Secondary scattering B meson duality
2014/12/23
I discuss some recent results on the systematic behavior of final state rescattering which makes use of the limit of a heavy B meson. The results suggest that soft final state interactions do not disa...
Chiral corrections to the vector and axial couplings of quarks and baryons
Vector the axial quark coupling lorentz covariance coupling control octet weight baryon matrix elements
2014/12/19
We calculate chiral corrections to the semileptonic vector and axial quark coupling constants using a manifestly Lorentz covariant chiral quark approach up to order O(p4) in the two- and three-flavor ...
NEWPORT NEWS, VA, Feb. 5, 2014 – From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matte...
Properties of quarks and mesons in the Dyson-Schwinger/Bethe-Salpeter approach
Dyson-Schwinger/Bethe-Salpeter mesons
2011/7/21
In this thesis, the Dyson-Schwinger - Bethe-Salpeter formalism is investigated and used to study the meson spectrum at zero temperature, as well as the chiral phase transition in finite-temperature QC...

Classical quarks in dual electromagnetic fields
Classical quarks dual electromagnetic fields
2011/1/18
Electromagnetic properties of quark-like particles are examined in a classical field model involving extended dual electromagnetic fields. These can have fractional charges and a confining potential t...
Heavy quarks and the collective properties of hot QCD

2011/10/11
Abstract: After reviewing the evidence that QCD matter at ultrarelativistic energies behaves as a very good fluid, we describe the connection of QCD fluidity to heavy quark observables. We review the ...

The theory unifying spin and charges and predicting families, proposed as a new way to explain the assumptions of the standard model of the electroweak and colour interactions, predicts at the low ene...
EOS in 2+1 flavor QCD with improved Wilson quarks by the fixed-scale approach
EOS 2+1 flavor QCD improved Wilson quarks
2011/1/6
We present the status of our study on the equation of state in 2+1 flavor QCD with non-perturbatively improved Wilson quarks coupled with the RG improved glue. We apply the T-integration method to non...
