Double Pulse Generator for Unipolar Discharges in Long Plasma Tubes for the AWAKE Experiment / Torrado, Nuno E (Lisbon, CFP ; CERN) ; Lopes, Nelson C (Lisbon, CFP) ; Silva, J Fernando A (Lisbon, IST) ; Amoedo, Carolina (CERN) ; Sublet, Alban (CERN)
High-voltage pulsed gas discharges can produce suitable plasma for wakefield particle acceleration experiments. Such plasmas are challenging loads characterized by significant parasitic elements and fast impedance transitions leading to hard-to-predict dynamic behavior. [...]

Applications of dispersive sum rules: $\epsilon$-expansion and holography / Carmi, Dean (EPFL, Lausanne, FSL ; Haifa U.) ; Penedones, Joao (EPFL, Lausanne, FSL) ; Silva, Joao A. (EPFL, Lausanne, FSL) ; Zhiboedov, Alexander (CERN)
We use Mellin space dispersion relations together with Polyakov conditions to derive a family of sum rules for Conformal Field Theories (CFTs). The defining property of these sum rules is suppression of the contribution of the double twist operators. [...]

On the possible virtual state nature of the LHCb Pc$(4312)^+$ signal / Silva-Castro, J.A. (Mexico U., ICN)
In this contribution we study the nature of the new Pc$(4312)^+$ signal reported by LHCb collaboration in the $J/\psi\,p$ spectrum. We use $S$-matrix principles to perform a minimum-bias analysis of the data, focusing on the analytic properties that can be related to the microscopic origin of the Pc$(4312)^+$ peak. [...]

Nonperturbative Mellin Amplitudes: Existence, Properties, Applications / Penedones, Joao (EPFL, Lausanne, FSL) ; Silva, Joao A. (EPFL, Lausanne, FSL) ; Zhiboedov, Alexander (CERN)
We argue that nonperturbative CFT correlation functions admit a Mellin amplitude representation. Perturbative Mellin representation readily follows. [...]

Khuri-Treiman equations for $3\pi$ decays of particles with spin / Albaladejo, M. (Jefferson Lab) ; Winney, D. (Indiana U.) ; Danilkin, I.V. (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA) ; Fernández-Ramírez, C. (Mexico U., ICN) ; Mathieu, V. (Madrid U.) ; Mikhasenko, M. (CERN) ; Pilloni, A. (ECT, Trento ; INFN, Genoa) ; Silva-Castro, J.A. (Mexico U., ICN) ; Szczepaniak, A.P. (Jefferson Lab ; Indiana U.) /JPAC Collaboration
Khuri-Treiman equations have proven to be a useful theoretical tool in the analysis of 3-body decays, specially into the $3\pi$ final state. In this work we present in full detail the necessary generalization of the formalism to study the decays of particles with arbitrary spin, parity, and charge conjugation. [...]

Interpretation of the LHCb $P_c$(4312)$^+$ Signal / Fernández-Ramírez, C. (Mexico U., ICN) ; Pilloni, A. (ECT, Trento ; Fond. Bruno Kessler, Trento ; INFN, Genoa) ; Albaladejo, M. (Jefferson Lab) ; Jackura, A. (Indiana U., CEEM ; Indiana U.) ; Mathieu, V. (Jefferson Lab) ; Mikhasenko, M. (CERN) ; Silva-Castro, J.A. (Mexico U., ICN) ; Szczepaniak, A.P. (Jefferson Lab ; Indiana U., CEEM ; Indiana U.) /JPAC Collaboration
We study the nature of the new signal reported by LHCb in the J/psi p spectrum. Based on the S-matrix principles, we perform a minimum-bias analysis of the underlying reaction amplitude, focusing on the analytic properties that can be related to the microscopic origin of the Pc(4312) peak. [...]
