Charged kaon electric polarizability from four-point functions in lattice QCD
Shayan Nadeem, Walter Wilcox, Frank X. Lee
We present a lattice QCD calculation of the electric polarizability of the charged kaon using a four-point function approach, which is the Euclidean analog of low-energy Compton sc…
Electric Polarizability of Charged Pions from nHYP Four-Point Functions
Benjamin Luke, Sudip Shiwakoti, Shayan Nadeem +3
Understanding a hadron's electric and magnetic polarizabilities allows one to access internal structural information. Traditionally, the external field two-point function method ha…
Electric Polarizability of Charged Kaons from Lattice QCD Four-Point Functions
Shayan Nadeem, Walter Wilcox, Frank X. Lee
We study the electric polarizability of a charged kaon from four-point functions in lattice QCD as an alternative to the background field method. Lattice four-point correlation fun…
Neutral pion polarizabilities from four-point functions in lattice QCD
Frank X. Lee, Walter Wilcox, Andrei Alexandru +2
We report a proof-of-principle lattice QCD simulation of the electric and magnetic polarizabilities for a neutral pion in the four-point function method. The results are based on t…
