The masses of the low-lying baryons are evaluated using a total of ten ensembles of dynamical twisted mass fermion gauge configurations. The simulations are performed using two degenerate flavors of light quarks, and a strange and a charm quark fixed to approximately their physical values. The light sea quarks correspond to pseudo scalar masses in the range of about 210 to 430 MeV. We use the Iwasaki improved gluonic action at three values of the coupling constant corresponding to lattice… 

Charmed bottom baryon spectroscopy from lattice QCD

In this study, we calculate the masses of baryons containing one, two, or three heavy quarks using lattice QCD. We consider all possible combinations of charm and bottom quarks, and compute a total

Towards the quark--gluon plasma Equation of State with dynamical strange and charm quarks

We present an ongoing project aimed at determining the thermodynamic Equation of State (EoS) of quark-gluon matter from lattice QCD with two generations of dynamical quarks. We employ the Wilson

Continuum limit of the D meson, Ds meson, and charmonium spectrum from Nf=2+1+1 twisted mass lattice QCD

We compute masses of $D$ meson, $D_s$ meson and charmonium states using $N_f=2+1+1$ Wilson twisted mass lattice QCD. All results are extrapolated to physical light quark masses, physical strange and

Approximate Hamiltonian for baryons in heavy-flavor QCD

Aiming at relativistic description of gluons in hadrons, the renormalization group procedure for effective particles (RGPEP) is applied to baryons in QCD of heavy quarks. The baryon eigenvalue

Gluon momentum fraction of the nucleon from lattice QCD

We perform a direct calculation of the gluon momentum fraction of the nucleon using maximally twisted mass fermion ensembles with $N_f=2+1+1$ flavors at a pion mass of about $370\,\mathrm{MeV}$ and a

Finite-temperature gluon spectral functions from $$N_f=2+1+1$$Nf=2+1+1 lattice QCD

The study of spectral properties is based on a novel Bayesian approach for the extraction of non-positive-definite spectral functions, and clear indications for the existence of a well defined quasi-particle peak are obtained.

Pion-Nucleon Sigma Term from Lattice QCD.

An analysis of the pion-nucleon σ-term σ_{πN} using six ensembles with 2+1+1-flavor highly improved staggered quark action generated by the MILC Collaboration shows that the leading contribution to the isoscalar scalar charge comes from Nπ and Nππ states.



I and i

There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
