Effective masses and magnetic moments of charmed baryons in asymmetric hot strange hadronic matter
In the present work, we have studied the masses and magnetic moments of <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mrow><a:mi>spin</a:mi><a:mo>−</a:mo><a:msup><a:mrow><a:mfrac><a:mrow><a:mn>1</a:mn></a:mrow><a:mrow><a:mn>2</a:mn></a:mrow></a:mfrac></a:mrow><a:mrow><a:mo>+</a:mo></a:mrow></a:msup></a:mrow></a:math> and <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"><c:mrow><c:mi>spin</c:mi><c:mo>−</c:mo><c:msup><c:mrow><c:mfrac><c:mrow><c:mn>3</c:mn></c:mrow><c:mrow><c:mn>2</c:mn></c:mrow></c:mfrac></c:mrow><c:mrow><c:mo>+</c:mo></c:mrow></c:msup></c:mrow></c:math> singly and doubly charmed baryons in the strange hadronic medium at finite temperature using the chiral SU(3) quark mean field model. The properties of baryons within the framework of the chiral SU(3) mean field model are defined in terms of constituent quark masses and energies, which are modified through the exchange of scalar fields <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"><e:mi>σ</e:mi></e:math>, <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" display="inline"><g:mi>ζ</g:mi></g:math>, and <i:math xmlns:i="http://www.w3.org/1998/Math/MathML" display="inline"><i:mi>δ</i:mi></i:math> and the vector fields <k:math xmlns:k="http://www.w3.org/1998/Math/MathML" display="inline"><k:mi>ω</k:mi></k:math>, <m:math xmlns:m="http://www.w3.org/1998/Math/MathML" display="inline"><m:mi>ρ</m:mi></m:math>, and <o:math xmlns:o="http://www.w3.org/1998/Math/MathML" display="inline"><o:mi>ϕ</o:mi></o:math>. The scalar-isovector field, <q:math xmlns:q="http://www.w3.org/1998/Math/MathML" display="inline"><q:mi>δ</q:mi></q:math>, and the vector-isovector field, <s:math xmlns:s="http://www.w3.org/1998/Math/MathML" display="inline"><s:mi>ρ</s:mi></s:math>, contribute when the medium has finite isospin asymmetry. We have calculated the effective masses of constituent quarks and charmed baryons in the nuclear and strange matter within the chiral SU(3) quark mean field model and have used these as the input in SU(4) constituent chiral quark model to compute the effective magnetic moments of these baryons. Considering the configuration mixing, the contributions of valence quarks, quark sea, and orbital angular momentum of quark sea have been considered explicitly to calculate the in-medium magnetic moments.
