A set of four Finite Energy QCD sum rules are used to determine the magnetic field dependence of the sum of the up- and down-quark masses of QCD, $(m_u + m_d)$, the pion decay constant $f_\pi$, the pion mass $m_\pi$, the gluon condensate, $\langle 0| \alpha_s\, G^2|0\rangle$, and the squared energy threshold for the onset of perturbative QCD, $s_0$, related to the Polyakov loop of lattice QCD. 
Magnetic field dependence of nucleon parameters from QCD sum rules
Finite energy QCD sum rules involving nucleon current correlators are used to determine several QCD and hadronic parameters in the presence of an external, uniform, large magnetic field. The
Magnetic effects of QCD parameters from fnite energy sum rules
One of the advantages of the fnite energy sum rules is the fact that every operator in the operator product expansion series can be selected individually by the use of an appropriate kernel function
Neutral and charged pion properties under strong magnetic fields in the NJL model
In the framework of the Nambu--Jona-Lasino (NJL) model, we study the effect of an intense external uniform magnetic field on neutral and charged pion masses and decay form factors. In particular, the
Magnetic renormalons in a scalar self-interacting λϕ4 theory
We present an analysis about the influence of an external magnetic field on renormalons in a self interacting theory $\lambda \phi ^{4}$. In the weak magnetic field region, using an appropriate
Diquarks and nucleons under strong magnetic fields in the NJL model
We study the description of nucleons and diquarks in the presence of a uniform strong magnetic field within the framework of the two-flavor Nambu-Jona--Lasinio (NJL) model. Diquarks are constructed
Light pseudoscalar meson masses under strong magnetic fields within the SU(3) Nambu–Jona-Lasinio model
We calculate the pole masses of pseudoscalar mesons in a strongly magnetized medium within the framework of the SU(3) Nambu-Jona–Lasinio model, using a magnetic fieldindependent regularization
Light mesons around critical end points in $T-\mu_B-\mu_I-eB$ space
Light mesons (σ, π0, π±) are investigated in T − μB − μI − eB space by using a two-flavor NJL model, which are related to the chiral symmetry restoration and pion superfluid phase transition. In T −

Determination of the temperature dependence of the up- and down-quark masses in QCD
The temperature dependence of the sum of the QCD up- and down-quark masses, (mu+md) and the pion decay constant, fπ, are determined from two thermal finite energy QCD sum rules for the
Finite Temperature QCD Sum Rules: a Review
The method of QCD sum rules at finite temperature is reviewed, with emphasis on recent results. These include predictions for the survival of charmonium and bottonium states, at and beyond the

We present a comprehensive analysis of the light condensates in QCD with $1+1+1$ sea quark flavors (with mass-degenerate light quarks of different electric charges) at zero and nonzero temperatures
Quark mass determinations in QCD
Recent progress on QCD sum rule determinations of the light and heavy quark masses is reported. In the light quark sector a major breakthrough has been made recently in connection with the historical
Analysis of the QCD spectrum and chiral symmetry breaking with varying quark masses
The meson spectrum of QCD is studied in the framework of nonperturbative QCD as a function of varying quark masses mq. It is shown that the total spectrum consists of two branches: 1) the standard
Quark deconfinement and gluon condensate in a weak magnetic field from QCD sum rules
We study QCD finite energy sum rules (FESR) for the axial-vector current correlator in the presence of a magnetic field, in the weak field limit and at zero temperature. We find that the perturbative
Up- and down-quark masses from finite-energy QCD sum rules to five loops
The up- and down-quark masses are determined from an optimized QCD finite-energy sum rule involving the correlator of axial-vector divergences, to five-loop order in perturbative QCD, and including
