In Memoriam Dr. André Mischke

open access: yesProceedings, 2019
André Mischke, a former organizer of the Hot Quarks international workshop, passed away at the age of 46 on Thursday 8 November 2018 due to a severe illness he fought for over a year. [...]

Exactly massless quarks on the lattice [PDF]

open access: yes, 1997
It is suggested that the fermion determinant for a vector-like gauge theory with strictly massless quarks can be represented on the lattice as det 1+V 2 , where V=X(X † X) −1/2 and X is the Wilson-Dirac lattice operator with a negative mass term.

Tomography of the Quark-Gluon-Plasma by Charm Quarks [PDF]

open access: yes, 2015
We study charm production in ultra-relativistic heavy-ion collisions by using the Parton-Hadron-String Dynamics (PHSD) transport approach. The initial charm quarks are produced by the Pythia event generator tuned to fit the transverse momentum spectrum ...

Potential Biomarkers for Disease Stratification and Prognosis Prediction in Pediatric Asthma: LCN2, sST2 and FGF21

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Pediatric asthma is a common chronic airway inflammatory disease, where accurate assessment of disease severity and prognosis prediction is crucial for treatment decisions. Currently, there is a lack of precise and effective biomarkers.

Open heavy flavor measurements at STAR

open access: yesEPJ Web of Conferences, 2015
In relativistic heavy ion collisions at RHIC, heavy quarks are expected to be created from initial hard scatterings. Since heavy quarks have large masses, long life time, and negligible annihilation due to their small population, the number of heavy ...

HARD QUARK-QUARK SCATTERING WITH EXCLUSIVE REACTIONS* [PDF]

open access: yesLe Journal de Physique Colloques, 1985
We present data from π-p → elastic and ρ-p final states for scattering at 90° center of mass, -t = 9 GeV2/c2. A large ρ-p signal is seen and the ρ- are strongly polarized. This polarization tests a QCD prediction that quarks cannot flip helicity. The test fails dramatically.

Performance of pyDock in 8th CAPRI: Energy‐Based Scoring Applied to Docking and AlphaFold Models

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The 8th CAPRI edition has shown a significant evolution in the field of protein–protein complex structure prediction. We have participated in all 11 targets proposed in this edition, involving domain‐domain, protein–protein, protein‐peptide, and protein‐DNA interactions, including homo‐ and hetero‐meric interfaces.

An Experimental Review on Elliptic Flow of Strange and Multistrange Hadrons in Relativistic Heavy Ion Collisions

open access: yesAdvances in High Energy Physics, 2016
Strange hadrons, especially multistrange hadrons, are good probes for the early partonic stage of heavy ion collisions due to their small hadronic cross sections.

Off-forward quark-quark correlation function [PDF]

open access: yesPhysical Review D, 2006
The properties of the non-forward quark-quark correlation function are examined. We derive constraints on the correlation function from the transformation properties of the fundamental fields of QCD occurring in its definition. We further develop a method to construct an ansatz for this correlator.

Bottom-quark fragmentation in top-quark decay [PDF]

open access: yesNuclear Physics B, 2002
We study the fragmentation of the b quark in top decay in NLO QCD, within the framework of perturbative fragmentation, which allows one to resum large logarithms $\sim\log (m_t^2/m_b^2)$. We show the b-energy distribution, which we compare with the exact ${\cal O} ( _S)$ result for a massive b quark.
