Six-dimensional chiral gauged Einstein-Maxwell supergravity admits a two-parameter rotating dyonic string solution whose near horizon limit is the direct product of three-dimensional Anti-De Sitter space and a squashed three-sphere <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><msup><mi>S</mi><mn>3</mn></msup></math>. For a particular relation between the two parameters, the solution preserves <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mn>1</mn><mo>/</mo><mn>2</mn></math> supersymmetry. We determine the complete Kaluza-Klein spectrum of the theory around these <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow><msub><mrow><mi>AdS</mi></mrow><mrow><mn>3</mn></mrow></msub></mrow></math> backgrounds. For the supersymmetric backgrounds, the states organize into infinite towers of long and short multiplets of <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>OSp</mi><mo stretchy="false">(</mo><mn>2</mn><mo stretchy="false">|</mo><mn>2</mn><mo stretchy="false">)</mo></math>. In a certain limit of parameters, both the supersymmetric and the nonsupersymmetric spectra exhibit scale separation. In the latter case there are five topologically massive vectors and five scalars retaining finite masses with integer conformal dimensions, and in the supersymmetric case there are supersymmetric partners with half integer conformal dimensions, while all other masses diverge.

Measurements include the jet cross section, as well as distributions of SoftDrop-groomed momentum fraction (<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><msub><mi>z</mi><mi>g</mi></msub></math>), charged-particle transverse momentum with respect to jet axis (<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><msub><mi>j</mi><mi>T</mi></msub></math>), and radial distributions of charged particles within jets (<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>r</mi></math>). Also measured was the distribution of <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>ξ</mi><mo>=</mo><mo>−</mo><mi>ln</mi><mo stretchy="false">(</mo><mi>z</mi><mo stretchy="false">)</mo></math>, where <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>z</mi></math> is the fraction of the jet momentum carried by the charged particle. The measurements are compared to theoretical next-to and next-to-next-to-leading-order calculations, the pythia and herwig event generators, and to other existing experimental results. Indicated from these measurements is a lower particle multiplicity in jets at RHIC energies when compared to models. Also noted are implications for future jet measurements with sPHENIX at RHIC as well as at the future Electron-Ion Collider.
