Particle Phenomenology
Top quark physics has now entered the precision era with billions of top pairs expected to be produced over the lifetime of the LHC. As such, the need for ever more accurate theory predictions continues to grow. Using a formalism derived from Soft Collienar Effective Theory (SCET), we present predictions for differential cross sections which incorporate the simultaneous resummation of soft and...

The latest update in the NNPDF series of PDF determinations, NNPDF3.1, includes
a great deal of new experimental information on proton structure determined by collaborations at the LHC and Tevatron. Several of these new datasets provide particular challenges to PDF fitters due to their high-precision nature. We shall discuss the impact upon PDF fits of these new measurements, including W and...

Diboson production at the LHC is already setting competitive bounds on anomalous triple gauge couplings (aTGC) for certain types of theories due to the increase in energy. Within the SMEFT, the leading contributions at high energy to this process depend on a combination of aTGC plus other operators. Until now the contribution of these other operators was negligible due to being very...

The spectroscopy of charmonium-like mesons with masses above the DD\bar threshold has been full of surprises, and their nature remains poorly understood [1]. The currently most compelling theoretical descriptions of the mysterious XYZ mesons attributes them to higher lying charmonium states [2], hybrid structure with a tightly bound diquark [3, 4] or a tetraquark [3, 5] core that strongly...

We study a holographic Einstein-Maxwell-dilaton model, which is adjusted to lattice QCD data for 2+1 flavors and physical quark masses for the equation of state and quark number susceptibility at zero baryo-chemical potential, to explore the resulting phase diagram over the temperature-chemical potential plane. A first-order phase transition sets in at a temperature of about 112 MeV and a...
