Session 3
- Juan Nieves (IFIC (Valencia))
We study hybryd mesons in the framework of the extended Linear Sigma Model (eLSM). In particular, we consider the ground-state hybrids (with exotic quantum numbers $1^-+$, to which $\Pi_1(1600)$ belongs, other members till unknown) and their (also unknown) axial-vector chiral partners. We evaluate both masses and decays of these hybrid mesons into conventional quark-antiquark states, such as...
In this talk I will review recent progress in the field of event shapes with massive particles. I will present "massive" schemes, emphasising their impact on the sensitivity to quark masses, and will show results for fixed-order and resummed computations up to $\rm N^2LL+ \mathcal{O}(\alpha_s)$ accuracy. For the 2-jettiness observable, cross sections at $\rm{N^3LL} + \mathcal{O}(\alpha_s^2)$...
