Radiative decays of the second shell Λ b and Ξ b bottom baryons

In this work, we investigate the radiative decays of the <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:msub> <a:mi mathvariant="normal">Λ</a:mi> <a:mi>b</a:mi> </a:msub> </a:math> and <d:math xmlns:d="http://www.w3.org/1998/Math/MathML" display="inline"> <d:msub> <d:mi mathvariant="normal">Ξ</d:mi> <d:mi>b</d:mi> </d:msub> </d:math> bottom baryons, which belong to the flavor antitriplet ( <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" display="inline"> <g:msub> <g:mover accent="true"> <g:mn mathvariant="bold">3</g:mn> <g:mo stretchy="false">¯</g:mo> </g:mover> <g:mi mathvariant="normal">F</g:mi> </g:msub> </g:math> ), within the constituent quark model formalism. The electromagnetic transitions are calculated from the second shell states to both the ground and <m:math xmlns:m="http://www.w3.org/1998/Math/MathML" display="inline"> <m:mi>P</m:mi> </m:math> -wave final states. These decays may help confirm the existence of certain resonances. Moreover, electromagnetic decay widths provide additional information that can be particularly useful for distinguishing resonances with the same mass and total decay width. This study presents, for the first time, the calculation of electromagnetic decays for <o:math xmlns:o="http://www.w3.org/1998/Math/MathML" display="inline"> <o:msub> <o:mi>D</o:mi> <o:mi>ρ</o:mi> </o:msub> </o:math> -wave states, <q:math xmlns:q="http://www.w3.org/1998/Math/MathML" display="inline"> <q:mi>ρ</q:mi> <q:mo>−</q:mo> <q:mi>λ</q:mi> </q:math> mixed states, and <s:math xmlns:s="http://www.w3.org/1998/Math/MathML" display="inline"> <s:mi>ρ</s:mi> </s:math> -mode radially excited states. Throughout our calculations, we account for uncertainties arising from both experimental and model-dependent errors.
