Here we discuss the pattern of the electromagnetic forces acting on a dipole and on a quadrupole coil. We first give an analytical estimate of the accumulation of prestress in the midplane for dipoles and quadrupoles based on sector coils [...] 2020 - 1:22:10.

Due to the very short time scale characterising their production, they experience the whole evolution of the system serving as Brownian-motion markers of the QGP [...] 2020 - 1:17:27.

To interpret the observed suppression in heavy-ion collisions, a good understanding of its production mechanism in p+p collisions is needed. [...] 2020 - 0:19:24.

On the other hand in high energy experiments (DIS) when probed by a small external probe, it behaves like an incoherent ensemble of (quasi-free) partons. [...] 2020 - 0:19:46.

Avoiding soft-emission approximations and working in the large-Nc limit, we consider corrections to the LPM effect from cases where the coherence lengths of two consecutive splittings overlap.

It was finally shown that semiclassical formulations of small x physics can have the form of an infinite twist framework involving Transverse Momentum Dependent (TMD) distributions in the eikonal limit.
