Emergence of high-energy dynamics from cascade-baryon detections at the LHC

Abstract
Abstract We propose the inclusive detection at the LHC of a cascade $$\Xi ^-/\bar{\Xi }^+$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msup><mml:mi>Ξ</mml:mi><mml:mo>-</mml:mo></mml:msup><mml:mo>/</mml:mo><mml:msup><mml:mover><mml:mrow><mml:mi>Ξ</mml:mi></mml:mrow><mml:mrow><mml:mo>¯</mml:mo></mml:mrow></mml:mover><mml:mo>+</mml:mo></mml:msup></mml:mrow></mml:math> baryon in association with a jet, as a novel probe channel for the QCD dynamics at high energies. We investigate the behavior of a selection of distributions, differential in rapidity, azimuthal angle and/or transverse momenta, calculated via the hybrid high-energy/collinear factorization encoding the full next-to-leading BFKL resummation of energy logarithms. We come out with the conclusion that the fragmentation mechanism underlying the production of $$\Xi ^-/\bar{\Xi }^+$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msup><mml:mi>Ξ</mml:mi><mml:mo>-</mml:mo></mml:msup><mml:mo>/</mml:mo><mml:msup><mml:mover><mml:mrow><mml:mi>Ξ</mml:mi></mml:mrow><mml:mrow><mml:mo>¯</mml:mo></mml:mrow></mml:mover><mml:mo>+</mml:mo></mml:msup></mml:mrow></mml:math> baryon states leads to stabilization effects of the resummation, similar to those recently observed in the context of heavy-flavor studies within the same formalism.
