From data to the analytic S-matrix: A Bootstrap fit of the pion scattering amplitude / Guerrieri, Andrea (CERN ; London, City U. ; Perimeter Inst. Theor. Phys. ; U. Padua (main)) ; Häring, Kelian (CERN ; Amsterdam U. ; EPFL, Lausanne, FSL) ; Su, Ning (Caltech ; MIT)
We propose a novel strategy to fit experimental data using a UV complete amplitude ansatz satisfying the constraints of Analyticity, Crossing, and Unitarity. [...]

 From C to Routed Circuits for FPGAs in Seconds / Guerrieri, Andrea (speaker) (HES-SO and EPFL) ; Guerrieri, Andrea (speaker)
Advancements in design automation technologies, such as high-level synthesis (HLS), have raised the input abstraction level and made the design entry process for FPGAs more friendly to software programmers. In contrast, the backend compilation process for implementing designs on FPGAs is considerably more lengthy compared to software compilation. [...]

Bootstrapping Strings / Guerrieri, Andrea (speaker)
The numerical S-matrix Bootstrap aims at establishing non-perturbative universal bounds on physical observables that can be extracted from scattering amplitudes in any dimension. In the first part of the talk, I will review our recent exploration of the space of supergravity amplitudes, and how String/M theory often appears close to the boundary of the allowed region. [...]

A Bootstrap Bridge Between QCD and Gravity / Guerrieri, Andrea (speaker)
The numerical S-matrix Bootstrap aims at establishing non-perturbative universal bounds on physical observables that can be extracted from scattering amplitudes in any dimension. In this talk, I will focus on dimensions greater or equal to four, focusing on three main topics: no-go theorems for supersymmetric quantum gravity, rigorous model dependent bounds on Higgs couplings, and Bootstrapping the QCD spectrum from physical pion scattering. [...]

Bounds on scattering of neutral Goldstones / Acanfora, Francesca (INOA, Florence) ; Guerrieri, Andrea (Perimeter Inst. Theor. Phys. ; U. Padua, Dept. Phys. Astron.) ; Häring, Kelian (CERN ; Ecole Polytechnique, Lausanne) ; Karateev, Denis (Geneva U., Dept. Theor. Phys.)
We study the space of $2\to 2$ scattering amplitudes of neutral Goldstone bosons in four space-time dimensions. We establish universal bounds on the first two non-universal Wilson coefficients of the low energy Effective Field Theory (EFT) for such particles. [...]

Rigorous bounds on the analytic S-matrix / Guerrieri, Andrea (speaker)
In this talk I will introduce a complementary approach to the non-perturbative S-matrix Bootstrap based on duality in optimization theory. In particular, I will focus on the problem of bounding the quartic coupling for gapped theories in 4-dimensions, both from above and below. The bounds obtained rely solely on proven analyticity properties and the numerical problem can be efficiently solved using SDPB..

Flux Tube S-matrix Bootstrap / Elias Miró, Joan (CERN) ; Guerrieri, Andrea L. (ICTP-SAIFR, Sao Paulo) ; Hebbar, Aditya (EPFL, Lausanne, FSL) ; Penedones, João (EPFL, Lausanne, FSL) ; Vieira, Pedro (Perimeter Inst. Theor. Phys. ; ICTP-SAIFR, Sao Paulo)
We bootstrap the S-matrix of massless particles in unitary, relativistic two dimensional quantum field theories. We find that the low energy expansion of such S-matrices is strongly constrained by the existence of a UV completion. [...]

Flavored tetraquark spectroscopy / Guerrieri, Andrea L. (INFN, Rome2 ; Rome U., Tor Vergata) ; Papinutto, Mauro (INFN, Rome ; Rome U.) ; Pilloni, Alessandro (INFN, Rome ; Rome U.) ; Polosa, Antonio D. (INFN, Rome ; Rome U.) ; Tantalo, Nazario (CERN ; INFN, Rome2 ; Rome U., Tor Vergata)
The recent confirmation of the charged charmonium like resonance Z(4430) by the LHCb experiment strongly suggests the existence of QCD multi quarks bound states. Some preliminary results about hypothetical flavored tetraquark mesons are reported. [...]
