Dear Nestor, dear conveners,
sorry for bothering you one day after the closing deadline for
abstracts. I've had some big family problems lately, and I lost track of
the DIS abstract deadline. My bad ...
I was wondering whether you could be kind enough to accept two more
abstract submissions, one from me and one from my PostDoc student Andrea
Simonelli, on some recent work we have done. We would like to submit
them to the spin physics and 3D structure working group WG5.
Thank you so much for your understanding and cooperation
Best regards
M. Boglione

Title: Phenomenological extraction of TMD fragmentation functions from
recent BELLE data
A new formalism for the factorization of the cross section for single
hadron production in e+e- annihilations is applied to the
phenomenological analysis of data recently measured by the BELLE
Collaboration. While performing a NLO - NNL perturbative calculation of
the perturbative part of the process, we examine and thoroughly discuss
the suitability of a number of possible ansatz to model the
non-perturbative part of this universal TMD fragmentation function,
showing the extent to which present experimental data can actually
constrain its shape and functional form in terms of z_h, P_T and thrust.
Speaker: A. Simonelli
Title: Thrust resummation and rapidity divergencies
Extending TMD factorization to thrust-dependent observables entails
difficulties ultimately associated with the behavior of soft radiation.
As a consequence, the definition of the TMDs has to be revised, while
keeping (and extending) its universality properties. Moreover, the
regularization of the rapidity divergences intertwines with the thrust
dependence, leading to a new kind of factorization theorem, with
unexpected features. In this talk, I will show how to properly factorize
the thrust distribution of e+e- annihilation into a single hadron, whose
transverse momentum is measured with respect to the thrust axis. The
cross section is presented at NLL-accuracy both in thrust and in
transverse momentum.

Dear colleagues,
The registration for DIS2022: XXIX International Workshop on
Deep-Inelastic Scattering and Related Subjects, to be held in Santiago
de Compostela, May 2nd-6th 2022, is opened. Please find the details of
registration, refund, student support, travel and accommodation and
COVID-related issues, in https://indico.cern.ch/event/1072533/.
We plan to hold the conference in person. The registration fee is 430
EUR before March 22th 2022, and 500 EUR thereafter. Those who cannot
attend in person because their institutions or countries do not allow
the travel, because they do not comply with the COVID-related
requirements to enter Spain, or because of medical reasons, are
invited to contact us at dis2022-registration(a)igfae.usc.es.
If the conference has to be moved online due to unforeseen
circumstances, a refund (minus bank transfer expenses) down to a
smaller online fee will be done.
Note also that the deadline for abstract submission has been extended
to February 20th 23:59 CET.
Please inform those colleagues who may not receive this email.
Best regards
Nestor Armesto for the LPC
P.S. We apologise to those who may receive this email more than once.
