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 e-mail address of the Workshop, diff2016 --at-- cs.infn.it. The copyright transfer is to be filled in and sent to Alessandro Papa by ordinary mail, fax or e-mail at the following address: Alessandro Papa Dipartimento di Fisica, Università della Calabria Ponte Bucci, cubo 31C I-87036 Arcavacata di Rende (Cosenza) Italy fax: +39 0984 494401 e-mail: 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.

for being able to keep sessions in time in spite of so many talks To the chairpersons Diffraction in ep collisions: Douglas Ross, Marta Ruspa Future machine, Overviews: Marcella Capua, Enrico Tassi Diffraction in hadron-hadron collisions (experiment): Christina Mesropian, Risto Orava Diffraction in hadron-hadron collisions (phenomenology/theory): Boris Kopeliovich Spin Physics: Mauro Anselmino, Jacques Soffer Diffraction in nuclear physics: Leszek Adamczyk, Alan Martin Progress in QCD: Jochen Bartels, Dmitry Ivanov for being able to keep sessions in time in spite of so many talks

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

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
