We construct the Lagrangian for an effective theory of highly energetic quarks with energy Q, interacting collinear and soft gluons. This has two low scales, transverse momentum particles, ${p}_{\ensuremath{\perp}},$ scale ${p}_{\ensuremath{\perp}}^{2}/Q.$ The heavy to light currents are matched onto operators in at one loop renormalization group equations corresponding Wilson coefficients solved. running is used sum Sudakov logarithms inclusive...

We construct an effective field theory valid for processes in which highly energetic light-like particles interact with collinear and soft degrees of freedom, using the decay $\stackrel{\ensuremath{\rightarrow}}{B}{X}_{s}\ensuremath{\gamma}$ near end point photon spectrum, ${x=2E}_{\ensuremath{\gamma}}{/m}_{b}\ensuremath{\rightarrow}1,$ as example.

Simulating quantum field theories is a flagship application of computing. However, calculating experimentally relevant high energy scattering amplitudes entirely on computer prohibitively difficult. It well known that such processes can be factored into pieces computed using established perturbative techniques, and which currently have to simulated classical Markov chain algorithms. These simulation approaches work capture many the salient features, but cannot all effects. To exploit...

At large coupling, this equivalent Kogut-Susskind electric representation, which known provide good description region. small our approach adjusts maximum magnetic field represented digitization as regime low-lying eigenstates become strongly peaked around zero field.

For gauge theories, widely used basis for relies on representations induced by underlying group, with truncation that keeps only set lowest dimensional representations. works well at large bare coupling, but becomes...
