Description

"Diffraction and Low-x 2024" is a joint effort between the Diffraction and Low-x meeting workshop series. The purpose of this 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 is the Hotel Tonnara Trabia, Palermo, Sicily, from September 8, afternoon to September 14, lunch time. It is planned to be in person only.

Diffraction is a biennial workshop dedicated to theoretical and experimental progress in diffractive processes at high energies. The previous events took place in Cetraro (2000), Alushta (2002), Cala Gonone (2004), Milos (2006), La Londe-les-Maures (2008), Otranto (2010), Lanzarote (2012), Primošten (2014), Acireale (2016).

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), Kolimpari (Crete, July 2008), Ischia (September 2009), Kavala (June 2010), Santiago de Compostela (June 2011), Paphos (Cyprus, June 2012), Eilat (June 2013), Kyoto (June 2014), Sandomierz (September 2015), Gyöngyös (June 2016), Bisceglie (June 2017), Nicosia (August 2019), Elba (September 2021), Leros (September 2023). 

The previous joint workshops "Diffraction and Low-x" were held in Reggio Calabria (2018), and then Corigliano Calabro (2022).

The registration deadline will be June 30 (new) and the abstract submission deadline is June 15 (new).

        Fragmentation of heavy quarks

        Heavy flavored mesons produced with high $p_T$ demonstrate specific features of the production mechanism, such as: (i) short time of gluon radiation by a highly virtual heavy quark; (ii) short formation time of the heavy flavored meson wave function; (iii) enhancement of the fragmentation function $D_{b/B}(z)$ at large fractional momenta $z\to 1$; (iv) short mean free path in the medium (no color transparency). In particular these features explain the observed very different $p_T$ dependences of the nuclear ratio $R_{AA}$ for $J/\psi$ produced directly and indirectly (from B-decays). Data for D-meson production are explained as well.
