Linking non-perturbative and perturbative approaches to fragmentation

12 May 2025, 09:00 → 13 May 2025, 17:00 Europe/Vienna

ÖAW Postsparkasse

Connecting non-perturbative methods and phenomenology is a newly emerging field which has seen successful applications to parton distribution functions (PDFs). Fragmentation and hadronization, on the other hand, are key to most precise and detailed phenomenology at colliders. They pose new challenges and open questions on how the two fields can be connected.

The aim of the workshop is to bring together experts in non-perturbative methods and the theory of factorization theorems, hadronization and collider cross sections to tackle this challenge. The main objective is to identify a path to a well-defined interface, as has been established for the PDF case, to transfer results between both areas.

This informal workshop aims at working towards such an interface, and identifying the challenges and possible approaches. We therefore invite a very small set of experts, whom each will have the opportunity to present own activities and ideas on the topic in an informal setting, including ample time for discussion.

The workshop is organized by the University of Graz and the Institute of High Energy Physics (HEPHY) of the Austrian Academy of Sciences. Due to its natuer the workshop will be by invitation only, but please do contact the organizers if you have are interested to join.

Venue:

The workshop will be hosted at HEPHY's premises in the historic Postsparkasse building at Georg-Coch-Platz 2, 1010 Vienna.

Accommodation:

Suggestions for hotels in good reach of the venue are

Ruby-Lissi

Magdas Hotel

Mercure Grand

Motel One Vienna Staatsoper

Travel:

Vienna has very good international flight and train connections. From the airport you can use the S-Bahn or the CAT train into the city centre. Get off at the stop "Landstrasse/Wien Mitte" from which you can reach the venue by a five to ten minute walk. From the main station take the main exit towards "Südtiroler Platz" and Tramline O towards "Bruno-Marek-Allee". Get off at "Landstrasse/Wien Mitte", as well (six stops).

ZOOM conection:

We will provide a ZOOM connection in due course to this indico page. Please also register such that we can email everyone with further details.
