1. Proceedings
The Proceedings of the Workshop will be published online by American Institute of Physics. All registered participants will have access to the online version, free of charge, for one year. Authors are informed that their contributions will not be accepted if already published elsewhere. Manuscripts should be prepared according to the instructions given at the Web site of AIP. The final outcome must be a single PDF file to be sent to the official address of the Workshop, diff at-- cs.infn.it. The copyright transfer is to be filled in and sent to Alessandro Papa by ordinary mail, fax or at the following address: Alessandro Papa Dipartimento di Fisica, Università della Calabria Ponte Bucci, cubo 31C I Arcavacata di Rende (Cosenza) Italy fax: papa -at- cs.infn.it The number of pages assigned for each contribution is 4 pages for a 20-min talk 5 pages for a 25-min talk 6 pages for a 30-min talk. Color pictures are allowed, at no additional cost. The sharp deadline for the submission is NOVEMBER 15, 2016.

7. Marcella Capua, Marco Rossi, Ada Solano, Enrico Tassi
To my Co-Organizers
Marcella Capua, Marco Rossi,
Ada Solano, Enrico Tassi
whose enormous work is shadowed by my pathological hyperactivism, but is not less important than mine
To Enrico and Marcella also for the decisive inspection of this hotel last spring
to Ada also for her precious suggestions as native Sicilian
to Ada and Marcella also for conceiving the nice logo
to Marco for his silent, but punctual attention to many essential details
Thanks also to Vittorio Romano, for filling many unpredictable gaps

8. Imagine an excursion without excursionists
To each and every of you
Imagine an excursion without excursionists
(especially if hardy as Samuel) …
… a coffee break without people drawing in the air Feynman diagrams with the free hand
… a social dinner without relaxed diners
(and without Alan’s speech)
… an auditorium without interesting talks …
Even the most accurate organization could not prevent all that from being a nightmare

of the next Diffraction workshop
