Dynamically restoring conformal invariance in (integrable) $\sigma$-models / Aliaj, Rigers (Athens U.) ; Sfetsos, Konstantinos (Athens U. ; CERN) ; Siampos, Konstantinos (Athens U.)
Integrable $\lambda$-deformed $\sigma$-models are characterized by an underlying current algebra/coset model CFT deformed, at the infinitesimal level, by current/parafermion bilinears. [...]

Single Photon Production at Hadron Colliders at NNLO QCD with Realistic Photon Isolation / Chen, X. (KIT, Karlsruhe, TP ; KIT, Karlsruhe, IAP) ; Gehrmann, T. (Zurich U.) ; Glover, E.W.N. (Durham U., IPPP) ; Höfer, M. (Munich U., ASC) ; Huss, A. (CERN) ; Schürmann, R. (Zurich U.)
Isolated photons at hadron colliders are defined by permitting only a limited amount of hadronic energy inside a fixed-size cone around the candidate photon direction. [...]

The last Complex WIMPs standing / Bottaro, Salvatore ; Buttazzo, Dario ; Costa, Marco ; Franceschini, Roberto ; Panci, Paolo ; Redigolo, Diego ; Vittorio, Ludovico
We continue the study of weakly interacting massive particles (WIMP) started in [arXiv:2107.09688], focusing on a single complex electroweak $n$-plet with non-zero hypercharge added to the Standard Model. [...]

PBH assisted search for QCD axion dark matter / Choi, Gongjun (CERN) ; Schiappacasse, Enrico D. (Jyvaskyla U. ; Helsinki Inst. of Phys. ; Rice U.)
The entropy production prior to BBN era is one of ways to prevent QCD axion with the decay constant $F_{a}\in[10^{12}{\rm GeV},10^{16}{\rm GeV}]$ from overclosing the universe when the misalignment angle is $\theta_{\rm i}=\mathcal{O}(1)$. [...]
