Low-rank optimization for semidefinite convex problems
M. Journée, F. Bach, P. -A. Absil +1
We propose an algorithm for solving nonlinear convex programs defined in terms of a symmetric positive semidefinite matrix variable . This algorithm rests on the factorization $…
Modern Particle Physics Event Generation with WHIZARD
J. Reuter, F. Bach, B. Chokoufe Nejad +4
We describe the multi-purpose Monte-Carlo event generator WHIZARD for the simulation of high-energy particle physics experiments. Besides the presentation of the general features o…
Top Physics in WHIZARD
J. Reuter, F. Bach, B. Chokoufe +5
In this talk we summarize the top physics setup in the event generator WHIZARD with a main focus on lepton colliders. This includes full six-, eight- and ten-fermion processes, fac…
QCD NLO with Powheg matching and top threshold matching in WHIZARD
J. Reuter, F. Bach, B. Chokoufe +3
We present the status of the automation of NLO processes within the event generator WHIZARD. The program provides an automated FKS subtraction and phase space integration over the…
WHIZARD 2.2 for Linear Colliders
W. Kilian, F. Bach, T. Ohl +1
We review the current status of the WHIZARD event generator. We discuss, in particular, recent improvements and features that are relevant for simulating the physics program at a f…
Low-rank optimization with trace norm penalty
B. Mishra, G. Meyer, F. Bach +1
The paper addresses the problem of low-rank trace norm minimization. We propose an algorithm that alternates between fixed-rank optimization and rank-one updates. The fixed-rank op…
