Scalar Mesons a0(1450) and sigma(600) from Lattice QCD
Nilmani Mathur, A. Alexandru, Y. Chen +7
We study the a0 and sigma mesons with the overlap fermion in the chiral regime with the pion mass as low as 182 MeV in the quenched approximation. After the eta'pi ghost states are…

The Negativity of the Overlap-Based Topological Charge Density Correlator in Pure-Glue QCD and the Non-Integrable Nature of its Contact Part
I. Horvath, A. Alexandru, J. B. Zhang +7
We calculate the lattice two-point function of topological charge density in pure-glue QCD using the discretization of the operator based on the overlap Dirac matrix. Utilizing dat…

Inherently Global Nature of Topological Charge Fluctuations in QCD
I. Horvath, A. Alexandru, J. B. Zhang +8
We have recently presented evidence that in configurations dominating the regularized pure-glue QCD path integral, the topological charge density constructed from overlap Dirac ope…
