IMPORTANT NEWS (July 10 2021)

Low x will  happen this Fall 2021 in person  Thanks to all participants!

Connection details:

A mandatory Green Pass is required for all attendees of the workshop.
Those who are not vaccinated will have to do the test every 48 hours.
Tests can be performed at the hotel at a cost of Euro 15.00 (but a certificate will not be issued).
If you need a certificate to return to your country of origin, it is possible to do it  in Portoferraio at a cost of Euro 50.00, and if you need an English translation, the cost will be Euro 60.00.

It is compulsory to wear masks in the common areas inside the hotel, but not in the conference room since there will be enough separation between people.


The best way to reach Elba is to fly to Rome, Florence or Pisa, and take the train to Piombino where you can take a ferry to Elba (there are ferries very often, every 30 minutes or so). A shuttle organized by the local organizers will come to pick you up at the harbour to go to the hotel.


The purpose of the Low-x workshop is to stimulate discussions between experimentalists and theorists in diffractive hadronic physics, QCD dynamics at low-x, parton saturation and exciting problems in QCD at HERA, Tevatron, LHC, RHIC and the future EIC.

The conference venue will be at Hotel La Biodola in Elba island in Italy from September 26th through October 1st 2020. Full boarding at the hotel (breakfast, lunch and dinner) will be included in the price of the hotel. By Summer timescale, we will confirm if the event can be in person or remote.

The fees will be about 200 Euros.

Low-x is an annual workshop whose spirit is to favour fruitful and informal discussions between experimentalists and theorists in low-x, diffractive hadronic physics and exciting problems in QCD at HERA, Tevatron and LHC.

The workshop will allow theorists and experimentalists from different areas (LHC, RHIC, EIC, HERA...) to meet and contribute together. The workshop is by invitation and about 70 physicists are expected to attend in order to favor exchanges between participants. Discussion sessions (about 2 hours per day) will be organized so that new ideas in theory or experiments can be further developed.


Low-x has been held since DESY (1993), then Saclay (May 1994), Cambridge (July 1995), Durham (June 1996), Madrid (June 1997), Berlin (June 1998), Tel Aviv (June 1999), Oxford (July 2000), Cracow (June 2001), Antwerpen (September 2002), Nafplio (June 2003), Prague (September 2004), Sinaia (June 2005), Lisbon (June 2006), Helsinki (September 2007), Crete (July 2008), Ischia (September 2009), Kavala (June 2010), Santiago de Compostela (June 2011), Cyprus (June 2012), Eilat (June 2013), Kyoto (June 2014), Sandomierz (September 2015), Gyongyos (June 2016), Bisceglie (June 2017), Reggio Calabria jointly with Diffraction 2018 (August 2018), Nicosia, Cyprus (August 2019).

The Workshop is organized and sponsored by the University of Kansas and by EMMI.
