Operator subspace based method for the extraction of higher energy levels in Lattice field theoretic systems
Ken-Ichi Ishikawa, Siddharth Ramesh Pandey
Given the importance of spectral analysis of lattice quantum field theory data, the advancement of techniques for the same remains critically important. Therefore, we propose an al…
Meson spectrum and low-energy constants in large- QCD
Claudio Bonanno, Margarita García Pérez, Antonio González-Arroyo +2
We present new non-perturbative results about the meson spectrum and the low-energy constants of QCD in the 't Hooft large- limit, with $N_{\scriptscriptstyle{\rm f…
Universal Features of Chiral Symmetry Breaking in Large- QCD
Claudio Bonanno, Margarita García Pérez, Antonio González-Arroyo +3
We investigate the universal features of chiral symmetry breaking in large- QCD by comparing non-perturbative determinations of the low-lying Dirac spectrum with chiral Random M…
Non-perturbative determination of meson masses and low-energy constants in large- QCD
Claudio Bonanno, Margarita García Pérez, Antonio González-Arroyo +2
We provide first-principles non-perturbative determinations of the low-lying meson mass spectrum of large- QCD in the 't Hooft limit , as w…
The perturbative computation of the gradient flow coupling for the twisted Eguchi-Kawai model with the numerical stochastic perturbation theory
Hironori Takei, Ken-Ichi Ishikawa, Masanori Okawa
The gradient flow method is a renormalization scheme in which the gauge field is flowed by the diffusion equation. The gradient flow scheme has benefits that the observables compos…
The gluino condensate of large- SUSY Yang-Mills
Claudio Bonanno, Pietro Butti, Margarita García Pérez +3
We present the first lattice determination of the SUSY Yang-Mills gluino condensate at large . We exploit large- twisted volume reduction, and present two de…
The mass of the gluino-glue bound state in large- Supersymmetric Yang-Mills theory
Claudio Bonanno, Margarita García Pérez, Antonio González-Arroyo +2
We provide a first-principles non-perturbative determination of the mass of the lightest gluino-gluon bound state (gluino-glue) in large- Supersymmetric Yang--Mi…
Estimate of virtual photon polarization due to the intense magnetic field in Pb-Pb collisions at the LHC energies
Kento Kimura, Nicholas J. Benoit, Ken-Ichi Ishikawa +2
We present the first numerical calculation of the virtual photon polarization and assess the feasibility of measuring the polarization via the anisotropic decay $γ^{*} \rightarrow…
Perturbative gradient flow coupling of the twisted Eguchi-Kawai model with the numerical stochastic perturbation theory
Ken-Ichi Ishikawa, Masanori Okawa, Hironori Takei
The gradient flow scheme has emerged as a prominent nonperturbative renormalization scheme on the lattice, where flow time is introduced to define the renormalization scale. In thi…
Nonperturbative determination of the supersymmetric Yang-Mills gluino condensate at large
Claudio Bonanno, Pietro Butti, Margarita García Pérez +3
We present the first nonperturbative large- calculation of the supersymmetric (SUSY) YangMills gluino condensate obtained by means of numeric…
