The determination of Parton Distribution Functions from a finite set of data is a typical example of an inverse problem. Inverse problems are notoriously difficult to solve, in particular when a robust determination of the uncertainty in the result i

The BESIII experiment at the Beijing Electron Positron collider, run as a ``hyperon factory'', recently reported the first measurement of the asymmetry parameter of the $\Lambda\to n\gamma$ decay and updated its branching fraction, which differs from

We review the study, on the lattice, of the Green-Schwarz gauge-fixed string action describing worldsheet fluctuations about the minimal surface holographically dual to the null cusp Wilson loop, useful to evaluate the cusp anomaly of N = 4 super Yan
Pulsar Timing Arrays (PTAs) have reported evidence for a stochastic gravitational wave (GW) background at nHz frequencies, possibly originating in the early Universe. We show that the spectral shape of the low-frequency (causality) tail of GW signals

The free scalar field is only conformally invariant when non-minimally coupled to gravity. In flat space this amounts to amending, or improving, the energy momentum tensor. A no-go theorem prohibits the improvement for Goldstone bosons, originating f

We compute the spectrum of the low-lying mesonic states with vector, scalar and pseudoscalar quantum numbers in QCD with one flavour. With three colours the fundamental and the two-index anti-symmetric representations of the gauge group coincide. The

The possibility that gauge theories with chiral symmetry breaking exhibit an infrared fixed point is explored. First, explicit symmetry breaking by a quark mass term and renormalisation group arguments, with reasonable assumptions, imply that the qua

We address the nonperturbative calculation of the inclusive decay rate of semileptonic $B_{(s)}$-meson decays from lattice QCD. Precise Standard-Model predictions are key ingredients in searches for new physics, and this type of computation may event

New thermal phase of QCD, featuring scale invariance in the infrared (IR), was proposed to exist both in the pure-glue (N$_f$=0) and the ``real-world" (N$_f$=2+1) settings. Among key aspects of the proposal is that the system in this {\em IR phase} s

The single baryon solution of V-QCD is numerically computed. The spectrum of spin and isospin modes is also computed by quantizing the light fluctuations around the baryon. It is shown that there is a partial restoration of chiral symmetry at the bar
