Nucleosynthesis and CMB bounds on photophilic ALPs: a fresh look / Escudero, Miguel (CERN) ; Garcia-Perez, Clara (CERN ; Zaragoza U.) ; Ovchynnikov, Maksym (CERN)
We provide a fresh look at the cosmological constraints on axion-like particles (ALPs) that couple predominantly to photons, focusing on lifetimes $τ_{a} \lesssim 10^{4}\, {\rm s}$ and masses $m_a\lesssim 10\,{\rm GeV}$. [...]

opbasis - a Python package to derive minimal operator bases / Husung, Nikolai (CERN ; Madrid, IFT ; Madrid, Autonoma U.)
Finding a complete and yet minimal on-shell basis of operators of a given mass-dimension that are compatible with a specific set of transformation properties is the first step in any Effective Field Theory description. [...]

Mainz, PRISMA) ; Risch, Andreas (Wuppertal U.) ; Wittig, Hartmut (Helmholtz Inst., Mainz ; Darmstadt, GSI ; U. Mainz, PRISMA)
We present an update of our lattice QCD determination of the hadronic contribution to the running of the electromagnetic coupling, $Δα_{\mathrm{had}}^{(5)}(-Q^2)$, and of the electroweak mixing angle in the space-like momentum region up to $Q^2=12\ \mathrm{GeV}^2$. [...]

The collective expansion of the quark-gluon plasma (QGP) created in heavy-ion collisions suggests that geometry-inspired approaches can be useful in extracting information about the QGP. [...]
