Advances in higher-order resummation and Parton Shower

Objective

Full exploitation of the LHC data, notably for Higgs precision measurements, traditional standard-model studies and certain BSM searches, relies on high-precision theoretical calculations. The most widely used kind of theoretical prediction is the parton-shower Monte Carlo approach (PSMC). This accounts for logarithmically enhanced contributions to all order in the coupling. While there has been much progress in the past decade in combining PSMC and fixed-order calculations, the logarithmic accuracy of the underlying parton shower has received much less attention.
This project will start by developing the technology to describe the structure of the perturbative calculations at next-to-next-to-leading logarithmic (NNLL) accuracy for processes that involve QCD radiation both off the initial and the final state particles. That understanding will provide the foundations to extend for the first time the accuracy of parton showers to NNLL accuracy for a broad class of observables.
Given recent developments in matching and merging of PSMCs with fixed order predictions, this will be of benefit not just for the intrinsic logarithmic accuracy of the shower but also facilitate future improvements in matching and merging, with resulting further improvements in LHC data extraction and interpretation.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

MSCA-IF-EF-ST - Standard EF

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
