Size of the pion from full lattice QCD with physical u , d , s and c quarks

- J. Koponen, Francis Bursa, C. Davies, R. Dowdall, G. Lepage
- Physics
- 23 November 2015

We present the first calculation of the electromagnetic form factor of the π meson at physical light
quark masses. We use configurations generated by the MILC collaboration including the effect of… Expand

Mass anomalous dimension in SU(2) with two adjoint fermions

- Francis Bursa, L. Debbio, L. Keegan, C. Pica, Thomas Pickup
- Physics
- 23 October 2009

We study SU(2) lattice gauge theory with two flavours of Dirac fermions in the adjoint representation. We measure the running of the coupling in the Schrodinger Functional (SF) scheme and find it is… Expand

Mesons in large-N QCD

- G. Bali, Francis Bursa, +4 authors M. Panero
- Physics
- 16 April 2013

A bstractWe present the results of a systematic, first-principles study of the spectrum and decay constants of mesons for different numbers of color charges N, via lattice computations. We restrict… Expand

SO(2N) and SU(N) gauge theories in 2 + 1 dimensions

- Francis Bursa, R. Lau, M. Teper
- Physics
- 22 August 2012

A bstractWe perform an exploratory investigation of how rapidly the physics of SO(2N) gauge theories approaches its N = ∞ limit. This question has recently become topical because SO(2N) gauge… Expand

Improved lattice spectroscopy of minimal walking technicolor

- Francis Bursa, L. Debbio, +6 authors Antonio Rago
- Physics
- 21 April 2011

We present a numerical study of spectroscopic observables in the SU(2) gauge theory with two adjoint fermions using improved source and sink operators. We compare in detail our improved results with… Expand

Mass anomalous dimension in SU(2) with six fundamental fermions

- Francis Bursa, L. Debbio, L. Keegan, C. Pica, Thomas Pickup
- Physics
- 19 July 2010

We simulate SU(2) gauge theory with six massless fundamental Dirac fermions. We mea- sure the running of the coupling and the mass in the Schrodinger Functional scheme. We observe very slow running… Expand

A simple approach towards the sign problem using path optimisation

- Francis Bursa, M. Kroyter
- Physics
- 13 May 2018

A bstractWe suggest an approach for simulating theories with a sign problem that relies on optimisation of complex integration contours that are not restricted to lie along Lefschetz thimbles. To… Expand

The meson spectrum in large-N QCD

- G. Bali, Francis Bursa, +4 authors M. Panero
- Physics
- 6 February 2013

We present lattice results on the meson spectrum and decay constants in large-N QCD. The results are obtained in the quenched approximation for N = 2, 3, 4, 5, 6, 7 and 17 and extrapolated to… Expand

Running of the coupling and quark mass in SU(2) with two adjoint fermions

- Francis Bursa, L. Debbio, L. Keegan, C. Pica, Thomas Pickup
- Physics
- 14 October 2009

We simulate SU(2) gauge theory with two massless Dirac fermions in the adjoint representation. We calculate the running of the Schroedinger Functional coupling and the renormalised quark mass over a… Expand
