Moments of parton distributions functions of the pion from lattice QCD using gradient flow
Anthony Francis, Patrick Fritzsch, Rohith Karur +7
We present a nonperturbative determination of the pion valence parton distribution function (PDF) moment ratios …
Gradient flow for parton distribution functions: first application to the pion
Anthony Francis, Patrick Fritzsch, Robert V. Harlander +9
Parton distribution functions (PDFs) are central to precision QCD phenomenology. Their Mellin moments can be computed on the lattice, but direct determinations using local operator…
The singlet scalar state in a chiral ensemble in with two fundamental flavours
Laurence Sebastian Bowes, Vincent Drach, Patrick Fritzsch +3
Composite Higgs models are a class of Beyond the Standard Model (BSM) models proposed to address the hierarchy and naturalness problems associated with the Standard Model (SM) Higg…
Determination of the pseudoscalar decay constant from SU(2) with two fundamental flavors
Laurence Sebastian Bowes, Vincent Drach, Patrick Fritzsch +3
The SU(2) gauge group with two fundamental flavors is a candidate for a composite Higgs extension of the Standard Model. Central to Higgs phenomenology is a non-perturbative determ…
Probing higher moments of pion parton distribution functions
Anthony Francis, Patrick Fritzsch, Rohith Karur +7
We present the first numerical investigation of the method proposed in Ref. [1] to utilize gradient flow to obtain precise determinations of higher moments of PDFs from lattice QCD…
