Fluctuations of conserved charges at finite temperature from lattice QCD
Szabolcs Borsanyi, Zoltan Fodor, Sandor D. Katz +3
We present the full results of the Wuppertal-Budapest lattice QCD collaboration on flavor diagonal and non-diagonal quark number susceptibilities with 2+1 staggered quark flavors,…
Error Bounds for the Sign Function
Andreas Frommer, Karsten Kahl, Thomas Lippert +1
The Overlap operator fulfills the Ginsparg-Wilson relation exactly and therefore represents an optimal discretization of the QCD Dirac operator with respect to chiral symmetry. Whe…
Nucleon sigma terms for 2+1 quark flavours
R. Horsley, Y. Nakamura, H. Perlt +7
QCD lattice simulations yield hadron masses as functions of the quark masses. From the gradients of the hadron masses the sigma terms can then be determined. We consider here dynam…
Strangeness Contribution to the Proton Spin from Lattice QCD
Gunnar S. Bali, Sara Collins, Meinulf Gockeler +8
We compute the strangeness and light-quark contributions Delta s, Delta u and Delta d to the proton spin in nf=2 lattice QCD at a pion mass of about 285 MeV and at a lattice spacin…
A lattice study of the strangeness content of the nucleon
G. S. Bali, S. Collins, M. Gockeler +9
We determine the quark contributions to the nucleon spin Delta s, Delta u and Delta d as well as their contributions to the nucleon mass, the sigma-terms. This is done by computing…
The finite temperature QCD transition in external magnetic fields
G. S. Bali, F. Bruckmann, G. Endrodi +5
The effect of an external magnetic field on the finite temperature transition of QCD is studied. We measure thermodynamic observables including the quark condensates and susceptibi…
QCD thermodynamics with Wilson fermions
Szabolcs Borsanyi, Zoltan Fodor, Christian Hoelbling +6
QCD is investigated at finite temperature using Wilson fermions in the fixed scale approach. A 2+1 flavor stout and clover improved action is used at four lattice spacings allowing…
The QCD phase diagram for external magnetic fields
G. S. Bali, F. Bruckmann, G. Endrodi +5
The effect of an external (electro)magnetic field on the finite temperature transition of QCD is studied. We generate configurations at various values of the quantized magnetic flu…
The strange and light quark contributions to the nucleon mass from Lattice QCD
Gunnar S. Bali, Sara Collins, Meinulf Gockeler +9
We determine the strangeness and light quark fractions of the nucleon mass by computing the quark line connected and disconnected contributions to the matrix elements m_q <N|qbar q…
Hyperon sigma terms for 2+1 quark flavours
R. Horsley, Y. Nakamura, H. Perlt +7
QCD lattice simulations determine hadron masses as functions of the quark masses. From the gradients of these masses and using the Feynman-Hellmann theorem the hadron sigma terms c…
Sigma term and strangeness content of octet baryons
S. Durr, Z. Fodor, T. Hemmert +11
By using lattice QCD computations we determine the sigma terms and strangeness content of all octet baryons by means of an application of the Hellmann-Feynman theorem. In addition…
Spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states for
G. Bali, S. Collins, S. Durr +18
We study the spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states. We use two sets of gauge configurations, one set fro…
The ratio m_c/m_s with Wilson fermions
Stephan Durr, Giannis Koutsou
We determine the quark mass ratio m_c/m_s on the lattice, using Wilson-type fermions. Configurations with N_f=2 dynamical clover-improved fermions by the QCDSF collaboration are us…
Topology of dynamical lattice configurations including results from dynamical overlap fermions
Falk Bruckmann, Nigel Cundy, Florian Gruber +2
We investigate how the topological charge density in lattice QCD simulations is affected by violations of chiral symmetry caused by the fermion action. To this end we compare latti…
Dirac and Pauli form factors from lattice QCD
S. Collins, M. Göckeler, Ph. Hägler +11
We present a comprehensive analysis of the electromagnetic form factors of the nucleon from a lattice simulation with two flavors of dynamical O(a)-improved Wilson fermions. A key…
Precision computation of the kaon bag parameter
S. Durr, Z. Fodor, C. Hoelbling +8
Indirect CP violation in K \rightarrow ππ decays plays a central role in constraining the flavor structure of the Standard Model (SM) and in the search for new physics. For many ye…
Twelve massless flavors and three colors below the conformal window
Zoltan Fodor, Kieran Holland, Julius Kuti +2
We report new results for a frequently discussed gauge theory with twelve fermion flavors in the fundamental representation of the SU(3) color gauge group. The model, controversial…
FK/Fpi from the Budapest-Marseille-Wuppertal Collaboration
A. Ramos, S. Durr, Z. Fodor +7
Based on a series of lattice calculations we determine the ratio FK/Fpi in QCD. With experimental data from kaon decay and nuclear double beta decay, we obtain a precise determinat…
