Flavored pions and kaons at next-to-leading order in mixed-action staggered chiral perturbation theory
Jon A. Bailey, Jongjeong Kim, Weonjong Lee +2
Different versions of improved staggered fermions can be used as valence quarks to reduce discretization effects in lattice QCD calculations while increasing statistics on existing…
Update on and with staggered quarks
Taegil Bae, Yong-Chull Jang, Hwancheol Jeong +11
We update our results for obtained using HYP-smeared staggered valence quarks on the MILC asqtad lattices. In the last year, we have added 5 new measurments on the fine ($a\a…
Beyond the Standard Model B-parameters with improved staggered fermions in QCD
Taegil Bae, Yong-Chull Jang, Hwancheol Jeong +10
We calculate the kaon mixing B-parameters for operators arising generically in theories of physics beyond the standard model. We use HYP-smeared improved staggered fermions on the…
Non-perturbative Renormalization of Bilinear Operators with Improved Staggered Quarks
Jangho Kim, Jongjeong Kim, Weonjong Lee +1
We present renormalization factors for the bilinear operators obtained using the non-perturbative renormalization method (NPR) in the RI-MOM scheme with improved staggered fermions…
Neutral kaon mixing from new physics: matrix elements in QCD
Taegil Bae, Yong-Chull Jang, Hwancheol Jeong +11
We present results for matrix elements of four-fermion operators arising generically in models of new physics. These are needed to constrain such models using the measured v…
Nucleon Charges and Electromagnetic Form Factors from 2+1+1-Flavor Lattice QCD
Tanmoy Bhattacharya, Saul D. Cohen, Rajan Gupta +3
We present lattice-QCD results on the nucleon isovector axial, scalar and tensor charges, the isovector electromagnetic Dirac and Pauli form factors, and the connected parts of the…
