Parton Distribution Functions, $\alpha_s$ and Heavy-Quark Masses for LHC Run II [PDF]
, 2017 We determine a new set of parton distribution functions (ABMP16), the strong coupling constant $\alpha_s$ and the quark masses $m_c$, $m_b$ and $m_t$ in a global fit to next-to-next-to-leading order (NNLO) in QCD. The analysis uses the $\overline{\mathrm{

Deep learning in color: towards automated quark/gluon jet discrimination [PDF]
Journal of High Energy Physics, 2016 Artificial intelligence offers the potential to automate challenging data-processing tasks in collider physics. To establish its prospects, we explore to what extent deep learning with convolutional neural networks can discriminate quark and gluon jets ...

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.

Applying Bayesian parameter estimation to relativistic heavy-ion collisions: simultaneous characterization of the initial state and quark-gluon plasma medium [PDF]
, 2016 We quantitatively estimate properties of the quark-gluon plasma created in ultrarelativistic heavy-ion collisions utilizing Bayesian statistics and a multiparameter model-to-data comparison.

Thermodynamics and energy loss in D dimensions from holographic QCD model
European Physical Journal C: Particles and Fields, 2022 We consider the holographic QCD model with a planar horizon in the D dimensions with different consistent metric solutions. We investigate the black hole thermodynamics, phase diagram and equations of state (EoS) in different dimensions.

Phase transition from hadronic matter to quark matter [PDF]
, 2006 We study the phase transition from nuclear matter to quark matter within the SU(3) quark mean field model and NJL model. The SU(3) quark mean field model is used to give the equation of state for nuclear matter, while the equation of state for color ...

Quark motional effects on the interquark potential in baryons [PDF]
, 2008 We study the heavy-heavy-light quark ($QQq$) system in a non-relativistic potential model, and investigate the quark motional effect on the inter-two-quark potential in baryons.

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 ...
