The QCD energy-momentum tensor on the lattice: non-perturbative renormalization with $N_f=3$ / Bresciani, Matteo (Trinity Coll., Dublin) ; Brida, Mattia Dalla (Milan Bicocca U. ; INFN, Milan Bicocca) ; Giusti, Leonardo (Milan Bicocca U. ; INFN, Milan Bicocca ; CERN) ; Hirasawa, Mitsuaki (Milan Bicocca U. ; INFN, Milan Bicocca) ; Pepe, Michele (INFN, Milan Bicocca) ; Virzì, Luca (Milan Bicocca U. ; INFN, Milan Bicocca)
We construct the traceless components of the energy-momentum tensor on the lattice for QCD with $N_f=3$ flavours, such that their correlation functions satisfy the appropriate Ward identities in the continuum limit. [...]

Spectral densities from Euclidean correlators via integral transforms: theoretical framework / Giusti, Leonardo (INFN, Milan Bicocca ; Milan Bicocca U. ; CERN) ; Saccardi, Matteo (INFN, Milan Bicocca ; Colorado State U.) ; Toniolo, Diego (INFN, Milan Bicocca ; Milan Bicocca U.)
Spectral densities link experimental measurements to dynamical properties of a quantum field theory which, in turn, can be resolved non-perturbatively from the Euclidean time-dependence of correlation functions. [...]

Mapping jet substructure in heavy-ion collisions with track functions / Barata, João (CERN) ; Go, Yeonju (Brookhaven Natl. Lab.) ; Pablos, Daniel (Oviedo U. ; ICTEA, Oviedo)
We investigate the dynamics of high-energy QCD cascades in heavy-ion collisions, focusing on modifications to jets' substructure induced by the presence of a quark-gluon plasma (QGP). [...]

Angular Analysis of $B \to D^{*}\ell \barν_{\ell}$ from Lattice and Experiment: $|V_{cb}|$ and New Physics Constraints / Bordone, Marzia (U. Mainz, PRISMA) ; Heald, Ollie (Southampton U.) ; Jüttner, Andreas (Southampton U. ; CERN)
We present a combined angular analysis within and beyond the Standard Model (SM) of experimental measurements for the $B \to D^{*}\ell \barν_{\ell}$ angular coefficients provided by the Belle collaboration, together with lattice-calculated hadronic form-factor data from the HPQCD, JLQCD, and FNAL/MILC collaborations.

Mainz, PRISMA) ; Gubernari, Nico (Bonn U., HISKP) ; Vladimirov, Daniel (Siegen U.)

We renormalise (and improve) the flavour non-singlet axial current, pseudo-scalar density, vector current and tensor current, as well as quark masses, in O(a) improved lattice QCD with three massless flavours and lattice spacings down to 0.01 fm. [...]

Quantum Resources and Wigner Symmetry in Nucleon-Nucleon Scattering from Effective Field Theory / Low, Ian (Northwestern U. ; Argonne) ; Richardson, Thomas R. (UC, Berkeley ; LBNL, NSD) ; Trifinopoulos, Sokratis (CERN ; Zurich U.)
We study quantum resources in the spin degrees of freedom, such as entanglement, stabilizer magic, and non-local magic, in low-energy nucleon-nucleon scattering through next-to-leading order in pionless effective field theory. [...]
