Magnetic polarizability of a charged pion from four-point functions in lattice QCD
Frank X. Lee, Walter Wilcox, Andrei Alexandru +1
Electromagnetic dipole polarizabilities are fundamental properties of a hadron that represent its resistance to deformation under external fields. For a charged hadron, the presenc…
Charged pion electric polarizability from four-point functions in lattice QCD
Frank X. Lee, Andrei Alexandru, Chris Culver +1
Polarizabilities reveal valuable information on the internal structure of hadrons in terms of charge and current distributions. For neutral hadrons, the standard approach is the ba…
Pole position of the resonance in a three-body unitary framework
Daniel Sadasivan, Andrei Alexandru, Hakan Akdag +6
Masses, widths, and branching ratios of hadronic resonances are quantified by their pole positions and residues with respect to transition amplitudes on the Riemann sheets of the c…
Higher order quantization conditions for two spinless particles
Frank X. Lee, Andrei Alexandru, Ruairí Brett
Lattice QCD calculations of scattering phaseshifts and resonance parameters in the two-body sector are becoming precision studies. Early calculations employed Lüscher's formula for…
Measuring charged particle polarizabilities on the lattice without background fields
Walter Wilcox, Frank X. Lee
We show how to compute electromagnetic polarizabilities of charged hadrons without the use of background fields in lattice QCD. The low-energy behavior of the Compton scattering am…
Three-body dynamics of the resonance from lattice QCD
Maxim Mai, Andrei Alexandru, Ruairí Brett +4
Resonant hadronic systems often exhibit a complicated decay pattern in which three-body dynamics play a relevant or even dominant role. In this work we focus on the res…
