Ω ( 2380 ) as a partner of the Ω ( 2012 )

We present a study of the <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:mi mathvariant="normal">Ω</a:mi> <a:mo stretchy="false">(</a:mo> <a:mn>2380</a:mn> <a:mo stretchy="false">)</a:mo> </a:math> resonance and show that it is consistent with a dynamically generated state arising from the <f:math xmlns:f="http://www.w3.org/1998/Math/MathML" display="inline"> <f:msup> <f:mover accent="true"> <f:mi>K</f:mi> <f:mo stretchy="false">¯</f:mo> </f:mover> <f:mo>*</f:mo> </f:msup> <f:msup> <f:mi mathvariant="normal">Ξ</f:mi> <f:mo>*</f:mo> </f:msup> </f:math> , <k:math xmlns:k="http://www.w3.org/1998/Math/MathML" display="inline"> <k:mi>ω</k:mi> <k:mi mathvariant="normal">Ω</k:mi> </k:math> , and <n:math xmlns:n="http://www.w3.org/1998/Math/MathML" display="inline"> <n:mi>ϕ</n:mi> <n:mi mathvariant="normal">Ω</n:mi> </n:math> interactions. In this picture, the <q:math xmlns:q="http://www.w3.org/1998/Math/MathML" display="inline"> <q:mi mathvariant="normal">Ω</q:mi> <q:mo stretchy="false">(</q:mo> <q:mn>2380</q:mn> <q:mo stretchy="false">)</q:mo> </q:math> is analogous to the <v:math xmlns:v="http://www.w3.org/1998/Math/MathML" display="inline"> <v:mi mathvariant="normal">Ω</v:mi> <v:mo stretchy="false">(</v:mo> <v:mn>2012</v:mn> <v:mo stretchy="false">)</v:mo> </v:math> , which is generated from the <ab:math xmlns:ab="http://www.w3.org/1998/Math/MathML" display="inline"> <ab:mover accent="true"> <ab:mi>K</ab:mi> <ab:mo stretchy="false">¯</ab:mo> </ab:mover> <ab:msup> <ab:mi mathvariant="normal">Ξ</ab:mi> <ab:mo>*</ab:mo> </ab:msup> </ab:math> and <fb:math xmlns:fb="http://www.w3.org/1998/Math/MathML" display="inline"> <fb:mi>η</fb:mi> <fb:mi mathvariant="normal">Ω</fb:mi> </fb:math> channels. The resulting mass, total width, and partial decay widths into the <ib:math xmlns:ib="http://www.w3.org/1998/Math/MathML" display="inline"> <ib:mover accent="true"> <ib:mi>K</ib:mi> <ib:mo stretchy="false">¯</ib:mo> </ib:mover> <ib:msup> <ib:mi mathvariant="normal">Ξ</ib:mi> <ib:mo>*</ib:mo> </ib:msup> </ib:math> and <nb:math xmlns:nb="http://www.w3.org/1998/Math/MathML" display="inline"> <nb:msup> <nb:mover accent="true"> <nb:mi>K</nb:mi> <nb:mo stretchy="false">¯</nb:mo> </nb:mover> <nb:mo>*</nb:mo> </nb:msup> <nb:mi mathvariant="normal">Ξ</nb:mi> </nb:math> channels are compatible with the available experimental data. We also discuss possible experimental observables that could provide further insight into the nature of this state.
