A Nonperturbative, Schwinger-Dyson-Equation Analysis of Quark Masses and Mixings in a Model with QCD and Higgs Interactions [PDF]
, 1994 The Landau gauge Schwinger-Dyson Equation for the quark self-energy is solved in the quenched ladder approximation for several cases of one- and two-quark-generations. The exchanges of Standard Model gluons and Higgs bosons are taken into account.

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

Several Effects Unexplained by QCD
Universe, 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 ...

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

Heavy Quark Fluorescence [PDF]
Physical 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

Polarization Effects In Hadron-Hadron Scatterings
Cumhuriyet 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 ...

Quark mass density- and temperature- dependent model for bulk strange quark matter [PDF]
, 2002 It is shown that the quark mass density-dependent model can not be used to explain the process of the quark deconfinement phase transition because the quark confinement is permanent in this model.

Physical 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.

European Physical Journal C: Particles and Fields, 2022 Jet-medium interaction involves two important effects: jet energy loss and medium response. The search for jet-induced medium excitations is one of the hot topics in jet quenching study in relativistic nuclear collisions.
