The spectrum of qubitized QCD: glueballs in a gauge theory
Andrei Alexandru, Paulo F. Bedaque, Ruairí Brett +1
Quantum simulations of QCD require digitization of the infinite-dimensional gluon field. Schemes for doing this with the minimum amount of qubits are desirable. We present a practi…
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…
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…
Higher order finite volume 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…
Three-body interactions from the finite-volume QCD spectrum
Ruairí Brett, Chris Culver, Maxim Mai +3
We perform a fit of the finite-volume QCD spectrum of three pions at maximal isospin to constrain the three-body force. We use the unitarity-based relativistic three-particle quant…
