Exploring continuous beta-ensembles: A Python implementation for random matrix spectral statistics
Dorin Weissman
We present an open-source Python package for sampling the Gaussian, Laguerre, Jacobi, and Circular -ensembles of random matrix theory. The package implements the Dumitriu--Edelm…
Multi-dimensional chaos II: String scattering amplitudes, curve repulsion, and RMT
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
Multi-dimensional chaos refers to processes described by erratic functions of several dynamical variables. In this letter we analyze the string scattering amplitudes of highly-exci…
High-Energy Pion Scattering in Holographic QCD: A Comparison with Experimental Data
Adi Armoni, Dorin Weissman
Following Polchinski and Strassler [1] and our previous work [2], we study high-energy pion scattering in the holographic QCD hard-wall model. In particular, we focus on comparing…
Multi-dimensional chaos I: Classical and quantum mechanics
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
We introduce the notion of multi-dimensional chaos that applies to processes described by erratic functions of several dynamical variables. We employ this concept in the interpreta…
High-Energy Fixed-Angle Meson Scattering and the Constituent Counting Rule in Holographic QCD
Adi Armoni, Bartosz Pyszkowski, Shigeki Sugimoto +1
We investigate the high-energy fixed-angle scattering of pions and -mesons in a bottom-up holographic QCD model. To this end, we generalise the approach of Polchinski and Strass…
A black hole effective theory for strongly interacting matter
Matti Jarvinen, Dorin Weissman
We establish a new tool for studying strongly coupled matter: an effective theory of black holes in gravity, which maps to a hydrodynamic description of field theories via the gaug…
From spectral to scattering form factor
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
We propose a novel indicator for chaotic quantum scattering processes, the scattering form factor (ScFF). It is based on mapping the locations of peaks in the scattering amplitude…
Measuring chaos in string scattering processes
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
We analyze the amplitudes of one highly excited string (HES) state with two or three tachyons in open bosonic string theory. We argue that these processes are chaotic by showing th…
Supersymmetric Quantum Chiral Higher Spin Gravity
Mirian Tsulaia, Dorin Weissman
We study quantum properties of supersymmetric N=1 and N=4 extensions of the four dimensional bosonic Chiral Higher Spin Gravities (HiSGRAs). We discuss the spectra, the classical a…
Measure for chaotic scattering amplitudes
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
We propose a novel measure of chaotic scattering amplitudes. It takes the form of a log-normal distribution function for the ratios of (consecutive) spacings…
Partonic behavior of string scattering amplitudes from holographic QCD models
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
We study the emergence of partonic behavior in scattering processes at large Mandelstam's variable from string amplitudes in holographic backgrounds. We generalize the approach…
Cubic Vertices for N=1 Supersymmetric Massless Higher Spin Fields in Various Dimensions
I. L. Buchbinder, V. A. Krykhtin, Mirian Tsulaia +1
Using the BRST approach to higher spin field theories we develop a generic technique for constructing the cubic interaction vertices for N=1 supersymmetric massless higher spin fie…
Deciphering the recently discovered tetraquark candidates around 6.9 GeV
Jacob Sonnenschein, Dorin Weissman
Recently a novel hadronic state of mass 6.9 GeV, that decays mainly to a pair of charmonia, was observed in LHCb. The data also reveals a broader structure centered around 6490 MeV…
On the quantization of folded strings in non-critical dimensions
Jacob Sonnenschein, Dorin Weissman
Classical rotating closed string are folded strings. At the folding points the scalar curvature associated with the induced metric diverges. As a consequence one cannot properly qu…
The scattering amplitude of stringy hadrons I: Strings with opposite charges on their endpoints
Jacob Sonnenschein, Dorin Weissman, Shimon Yankielowicz
In this note we describe hadrons: mesons and baryons as strings with electric charges on their endpoints. We consider here only the neutral system with opposite charges coupled to…
Excited mesons, baryons, glueballs and tetraquarks: Predictions of the Holography Inspired Stringy Hadron model
Jacob Sonnenschein, Dorin Weissman
In this note we collect and summarize the predictions of the Holography Inspired Stringy Hadron (HISH) model. We list the masses and widths of predicted excited states across the s…
Quantizing the rotating string with massive endpoints
Jacob Sonnenschein, Dorin Weissman
We compute leading order quantum corrections to the Regge trajectory of a rotating string with massive endpoints using semiclassical methods. We expand the bosonic string action ar…
The decay width of stringy hadrons
Jacob Sonnenschein, Dorin Weissman
In this paper we further develop a string model of hadrons by computing their strong decay widths and comparing them to experiment. The main decay mechanism is that of a string spl…
A tetraquark or not a tetraquark: A holography inspired stringy hadron (HISH) perspective
Jacob Sonnenschein, Dorin Weissman
We suggest to use the state , which decays predominantly to , as a window to the landscape of tetraquarks. We propose a simple criterion to decide whether a st…
Glueballs as rotating folded closed strings
Jacob Sonnenschein, Dorin Weissman
In previous papers we argued that mesons and baryons can be described as rotating open strings in holographic backgrounds. Now we turn to closed strings, which should be the duals…
A rotating string model versus baryon spectra
Jacob Sonnenschein, Dorin Weissman
We continue our program of describing hadrons as rotating strings with massive endpoints. In this paper we propose models of baryons and confront them with the baryon Regge traject…
Rotating strings confronting PDG mesons
Jacob Sonnenschein, Dorin Weissman
We revisit the model of mesons as rotating strings with massive endpoints and confront it with meson spectra. We look at Regge trajectories both in the (J,M2) and (n,M2) planes, wh…
