at non-zero recoil
A. Vaquero, C. DeTar, A. X. El-Khadra +3
The current status of the lattice-QCD calculations of the form factors of the semileptonic decay is reviewed. Particular emphasis is given to the most mature cal…
at non-zero recoil
Alejandro Vaquero Avilés-Casco, Carleton DeTar, Aida X. El-Khadra +3
We present preliminary blinded results from our analysis of the form factors for decay at non-zero recoil. Our analysis includes 15 MILC asqtad ensembles…
Proton and neutron electromagnetic form factors from lattice QCD
C. Alexandrou, S. Bacchio, M. Constantinou +5
The electromagnetic form factors of the proton and the neutron are computed within lattice QCD using simulations with quarks masses fixed to their physical values. Both connected a…
Strange nucleon electromagnetic form factors from lattice QCD
C. Alexandrou, M. Constantinou, K. Hadjiyiannakou +4
We evaluate the strange nucleon electromagnetic form factors using an ensemble of gauge configurations generated with two degenerate maximally twisted mass clover-improved fermions…

A. Vaquero Avilés-Casco, C. DeTar, D. Du +4
We present preliminary results from our analysis of the form factors for the decay at non-zero recoil. Our analysis includes 15 MILC…
The nucleon spin and momentum decomposition using lattice QCD simulations
C. Alexandrou, M. Constantinou, K. Hadjiyiannakou +5
We determine within lattice QCD, the nucleon spin carried by valence and sea quarks, and gluons. The calculation is performed using an ensemble of gauge configurations with two deg…
Nucleon electromagnetic form factors using lattice simulations at the physical point
Constantia Alexandrou, Martha Constantinou, Kyriakos Hadjiyiannakou +4
We present results for the nucleon electromagnetic form factors using an ensemble of maximally twisted mass clover-improved fermions with pion mass of about 130 MeV. We use multipl…
Nucleon axial form factors using lattice QCD simulations with a physical value of the pion mass
Constantia Alexandrou, Martha Constantinou, Kyriakos Hadjiyiannakou +4
We present results on the nucleon axial and induced pseudo-scalar form factors using an ensemble of two degenerate twisted mass clover-improved fermions generated at the physical v…
Nucleon scalar and tensor charges using lattice QCD simulations at the physical value of the pion mass
C. Alexandrou, M. Constantinou, P. Dimopoulos +9
We present results on the light, strange and charm nucleon scalar and tensor charges from lattice QCD, using simulations with flavors of twisted mass Clover-improved fermio…
Direct Evaluation of the Quark Content of Nucleons from Lattice QCD at the Physical Point
A. Abdel-Rehim, C. Alexandrou, M. Constantinou +5
We evaluate the light, strange and charm scalar content of the nucleon using one lattice QCD ensemble generated with two degenerate light quarks with mass fixed to their physical v…
Implementation of the twisted mass fermion operator in the QUDA library
Alexei Strelchenko, Constantia Alexandrou, Giannis Koutsou +1
We discuss an extension of the QUDA library for the Wilson twisted mass operator. A performance analysis is presented for both degenerate and non-degenerate flavor doublets. The de…
