Quark decay top to two bodies

open access: yesVisión Electrónica, 2019
Is investigated the top quark decay (t) two bodies using the spectator model. Is analyzed the decay (t→bW⁺) calculated theoretically the width of decay and decay fraction of the particle whose result is compared with the experimental data of the table ...

Measurements of the Production, Decay and Properties of the Top Quark: A Review [PDF]

open access: yes, 2012
With the full Tevatron Run II and early LHC data samples, the opportunity for furthering our understanding of the properties of the top quark has never been more promising.

Thermoelectric properties of the (an-)isotropic QGP in magnetic fields

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The Seebeck effect and the Nernst effect, which reflect the appearance of electric fields along x-axis and along y-axis ( $$E_{x}$$ E x and $$E_{y}$$ E y ), respectively, induced by the thermal gradient along x-axis, are studied in the QGP at an external

Several Effects Unexplained by QCD

open access: yesUniverse, 2018
Several new experimental discoveries in high energy proton interactions, yet unexplained by QCD, are discussed in the paper. The increase of the cross sections with increasing energy from ISR to LHC, the correlation between it and the behavior of the ...

Quark scalar, axial, and pseudoscalar charges in the Schwinger-Dyson formalism [PDF]

open access: yes, 2014
We calculate the scalar, axial, and pseudoscalar charges of the quark in the Schwinger-Dyson formalism of Landau gauge QCD. It is found that the dressed quark scalar density of the valence quark is significantly enhanced against the bare quark ...

Polarization Effects In Hadron-Hadron Scatterings

open access: yesCumhuriyet Science Journal, 2018
In the case of diffraction scattering of hadrons by hadrons, a nonzeropolarization of the scattered particles arises, which is related to thelogarithmic derivative of the differential scattering cross section.Polarization changes sign in those reactions ...

Parton splitting scales of reclustered large-radius jets in high-energy nuclear collisions

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We carry out the first theoretical investigation on yields and the hardest parton splitting of large-radius jets reclustered from small radius ( $$R=0.2$$ R = 0.2 ) anti- $$k_t$$ k t jets in Pb + Pb collisions, and confront them with the recent ATLAS ...

Heavy Quark Fluorescence [PDF]

open access: yesPhysical Review Letters, 2010
Heavy hadrons containing heavy quarks (for example, Upsilon-mesons) feature a scale separation between the heavy quark mass (about 4.5 GeV for the b-quark) and the QCD scale (about 0.3 GeV}) that controls effective masses of lighter constituents. Therefore, as in ordinary molecules, the de-excitation of the lighter, faster degrees of freedom leaves the

Heavy quark solitons [PDF]

open access: yesPhysical Review D, 1993
We investigate the heavy baryons which arise as solitonic excitations in a ``heavy meson" chiral Lagrangian which includes the light vector particles. It is found that the effect of the light vectors may be substantial. We also present a simple derivation which clearly shows the connection to the Callan-Klebanov approach.
