Charm quark mass using a massive nonperturbative renormalisation scheme
/ Del Debbio, Luigi (Piemonte Orientale U., Alessandria ; INFN, Turin) ; Erben, Felix (CERN) ; Flynn, Jonathan (Southampton U.) ; Mukherjee, Rajnandini (Southampton U.) ; Tsang, J. Tobias (CERN)
We present a first numerical implementation of a massive nonperturbative renormalisation scheme, RI/mSMOM, in the study of heavy quarks using the domain-wall fermion action. In particular, we calculate renormalisation constants for fermion bilinears at non-vanishing heavy-quark masses and compare the approach to the continuum of the renormalised charm-quark mass with that from a mass-independent scheme..

Towards the super Yang-Mills spectrum at large $N_c$
/ Martins, Sofie (Odense U.) ; Della Morte, Michele (Odense U.) ; Jäger, Benjamin (Odense U.) ; Tsang, Justus Tobias (CERN) ; Ziegler, Felix Paul Gerhard (Edinburgh U.)
We examine one-flavour $SU(N_c)$ gauge theories, where $N_c$ denotes the number of colors, with one fermion in the antisymmetric representation as a candidate to approximate $\mathcal{N}=1$ super Yang Mills due to their equivalence in the large-$N_c$ limit. Summarising results on spectral evaluations of $N_c=3$, we will report on the progress of dynamical calculations for $N_c>3$. [...]

Workshop summary: Kaons@CERN 2023
/ Anzivino, G. (INFN, Perugia ; Perugia U.) ; Cuendis, Sergio Arguedas (Costa Rica U.) ; Bernard, V. (IJCLab, Orsay) ; Bijnens, J. (Lund U.) ; Bloch-Devaux, B. (Turin U.) ; Bordone, M. (CERN) ; Brizioli, F. (INFN, Perugia ; CERN) ; Brod, J. (Cincinnati U.) ; Camalich, J.M. (IAC, La Laguna ; Laguna U., Tenerife) ; Ceccucci, A. (CERN) et al.
Kaon physics is at a turning point -- while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the opportunities these experiments and theoretical developments provide for particle physics in the coming decade and beyond.

Spectrum of QCD with one flavor: A window for supersymmetric dynamics
/ Della Morte, Michele (Southern Denmark U., CP3-Origins) ; Jäger, Benjamin (Southern Denmark U., CP3-Origins ; U. Southern Denmark, Odense, DIAS) ; Sannino, Francesco (Southern Denmark U., CP3-Origins ; U. Southern Denmark, Odense, DIAS ; Naples U.) ; Tsang, Justus Tobias (CERN ; Southern Denmark U., CP3-Origins) ; Ziegler, Felix P.G. (Edinburgh U.)
We compute the spectrum of the low-lying mesonic states with vector, scalar and pseudoscalar quantum numbers in QCD with one flavour. With three colours the fundamental and the two-index anti-symmetric representations of the gauge group coincide. [...]
