Sudakov logs and power corrections for selected event shapes

open access: yes, 2004
I summarize the results of recent studies analyzing perturbative and nonperturbative effects of soft gluon radiation on the distributions of the C-parameter and of the class of angularities, by means of dressed gluon exponentiation.Comment: Talk given at

Equivalence of effective actions

open access: yesJournal of High Energy Physics
For the same quantum field theory distinct effective actions can be obtained by coupling sources to different choices of field variables. This is the same as considering effective actions for theories related by a change of variables and thus differ only

Nonperturbative correlation functions from homotopy algebras

open access: yesJournal of High Energy Physics
The formula for correlation functions based on quantum A ∞ algebras in arXiv:2203.05366, arXiv:2305.11634, and arXiv:2305.13103 requires us to divide the action into the free part and the interaction part.
