Supporting the search for the CEP location with nonlocal PNJL models constrained by lattice QCD
We investigate the possible location of the critical endpoint in the QCD phase diagram based on nonlocal covariant PNJL models including a vector interaction channel. The form factors of the covariant interaction are ...
Compatibility of a model for the QCD-Pomeron and chiral-symmetry breaking phenomenologies
The phenomenology of a QCD-Pomeron model based on the exchange of a pair of non-perturbative gluons, i.e. gluon fields with a finite correlation length in the vacuum, is studied in comparison with the phenomenology of QCD ...
Comparison between the continuum threshold and the Polyakov loop as deconfinement order parameters
(American Physical Society, 2017-02)
We study the relation between the continuum threshold s0 within finite energy sum rules and the trace of the Polyakov loop Φ in the framework of a nonlocal SU(2) chiral quark model, establishing a contact between both ...
Modification of the B meson mass in a magnetic field from QCD sum rules
(Amer Physical Soc, 2014-04-10)
In this paper, we extend the well-known QCD sum rules used in the calculation of the mass of heavy mesons to estimate the modification of the charged B-meson mass, m(B), in the presence of an external Abelian magnetic ...
Insights into the Quark-Gluon Vertex from Lattice QCD and Meson Spectroscopy
By comparing successful quark-gluon vertex interaction models with the corresponding interaction extracted from lattice-QCD data on the quark's propagator, we identify common qualitative features which could be important ...
Parton-to-kaon fragmentation revisited
(American Physical Society, 2017-05)
We revisit the global QCD analysis of parton-to-kaon fragmentation functions at next-to-leading-order accuracy using the latest experimental information on single-inclusive kaon production in electron-positron annihilation, ...
Uncertainties in pion and kaon fragmentation functions
(American Physical Society, 2012-10)
We present a detailed assessment of uncertainties in parton-to-pion and parton-to-kaon fragmentation functions obtained in recent global QCD analyses of single-inclusive hadron production data at next-to-leading order ...
Higgs boson production at the LHC: Transverse-momentum resummation and rapidity dependence
(Elsevier Science, 2008-03)
We consider Higgs boson production by gluon fusion in hadron collisions. We study the doubly-differential transverse-momentum (qT) and rapidity (y) distribution of the Higgs boson in perturbative QCD. In the region of small ...
Probing the sea quark content of the proton with one-particle-inclusive processes
(American Physical Society, 2017-11)
We investigate the feasibility of constraining parton distribution functions in the proton through a comparison with data on semi-inclusive deep-inelastic lepton-nucleon scattering. Specifically, we reweight replicas of ...
