Search for medium response to jet quenching via hadron chemistry around the quenched jets [PDF]
EPJ Web of ConferencesWe present a unique signal of medium response to jet quenching: the enhancement of baryon-to-meson ratios for associated particles at intermediate transverse momentum around the triggered quenched jets.

Global aspects of the scalar meson puzzle [PDF]
, 2009 A generalized linear sigma model for low energy QCD is employed to study the quark structure of eight low lying scalar isomultiplets as well as eight low lying pseudoscalar isomultiplets.

Multiple Parton Scattering in Nuclei: Heavy Quark Energy Loss and Modified Fragmentation Functions [PDF]
, 2004 Multiple scattering, induced radiative energy loss and modified fragmentation functions of a heavy quark in nuclear matter are studied within the framework of generalized factorization in perturbative QCD. Modified heavy quark fragmentation functions and

A Novel Multi-Gene Detection Platform for the Analysis of miRNA Expression
Scientific Reports, 2018 The study of miRNAs and their roles as non-invasive biomarkers has been intensely conducted in cancer diseases over the past decade. Various platforms, ranging from conventional qPCRs to Next Generation Sequencers (NGS), have been widely used to analyze ...

Instanton vacuum at finite density of quark matter [PDF]
, 2002 We study light quark interactions in the instanton liquid at finite quark/baryon number density analyzing chiral and diquark condensates and investigate the behaviors of quark dynamical mass and both condensates together with instanton liquid density as ...

The Quark Spin Distributions of the Nucleon
, 1998 The quark helicity measured in polarized deep inelastic scattering is different from the quark spin in the rest frame of the nucleon. We point out that the quark spin distributions $\Delta q_{RF}(x)$ are connected with the quark helicity distributions ...

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

Gauge-Invariant Decomposition of Nucleon Spin and Its Spin-Off
, 1996 I introduce a gauge invariant decomposition of the nucleon spin into quark helicity, quark orbital, and gluon contributions. The total quark (and hence the quark orbital) contribution is shown to be measurable through virtual Compton scattering in a ...

European Physical Journal C: Particles and Fields, 2022 We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charged leptons ...
