As a consequence of the increasingly large flux of partons at small x, Double Parton Interactions (DPI) play an increasingly important role at high energies. A detail understanding of DPI dynamics is therefore mandatory, for a reliable subtraction of the background in the search of new physics...
Calculations that aim to describe these extreme regions of phase space should in principle include resummation in the calculations of matrix elements and should make use of PDFs that were determined with a consistent theory. Threshold (large-x) resummation has already been included in PDF fits [...
38] for further studies), which in principle enter due to splittings of the formγ→ll¯. As these are not present in the MSHT framework the inclusion of lepton loops inPγγwould in particular lead to some small amount of violation...
Thus, the proton can also play the role of quantum bound state. Unlike the hydrogen atom, the proton can be accelerated and its speed can become very close to that of light, as illustrated in this figure: Feynman's Parton Picture In 1964, Murray Gell-Mann invented the quark model in...
Parton distributions on the lightcone are mandatory inputs in high energy scattering and play an important role in searching for new physics at high energy. The large momentum effective theory allows one to access the PDFs from first principle Lattice QCD. In this talk, I will review the rece...
“Dolly is not only my idol because of her incomparable career. She’s also my role model because of her steadfast morals and values,” Parton writes. “At her core, she is the definition of a humanitarian ... “There’s a theory that you shouldn’t meet your heroes,” Cyrus continue...

{u}}\). We briefly discuss the treatment of deuteron and nuclear corrections, of the heavy flavour PDFs and of the experimental errors of the data, even though there are no major changes in these cases. We discuss in more depth the inclusion, for the first time, of full NNLO theory ...
Double hard scattering can play an important role for producing multiparticle final states in hadron-hadron collisions. The associated cross sections depend on double parton distributions, which at present are only weakly constrained by theory or measurements. A set of sum rules for these distributions...
