Leros island, Greece

Crithoni's Paradise 4* Hotel

Description

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 the Crithoni's paradise hotel, Leros Island, Greece, from September 4 in the morning to September 8 in the evening Please register as soon as possible since this is still a highly touristic hotel and region. The reservation will be fully inclusive with breakfast, lunch and dinner at the hotel. It is also advised to buy the flight tickets as soon as possible to secure availability and avoid high prices.

Please note that you might receive a mail from ops@travellerpoint.org about the hotel reservation, THIS IS A SPAM AND DO NOT ANSWER THEM!!!!!

The registration fee will be 250 Euros for participants of the workshop, and 120 Euros for companions. The fees cover the conference room, all coffee breaks, the workshop dinner, the transfer from the harbour/airport and back, the welcome drinks as well as a one-day tour.

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. 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 (August 2018), Nicosia (August 2019), and Elba (September 2021)

The Workshop is organized and sponsored by the University of Kansas, the University of Cyprus, ExtreMe Matter Institute at GSI (EMMI) and CERN
