Can the X(1750) be a <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>ϕ</mml:mi><mml:mo stretchy="false">(</mml:mo><mml:mn>1750</mml:mn><mml:mo stretchy="false">)</mml:mo></mml:math>?
We present the arguments that the X(1750) has the isospin <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mi>I</a:mi><a:mo>=</a:mo><a:mn>0</a:mn></a:math>, and as such, it belongs to the <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"><c:mi>ϕ</c:mi></c:math> family. We base our argument on the X(1750) appearing in the <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"><e:mrow><e:msup><e:mrow><e:mi>e</e:mi></e:mrow><e:mrow><e:mo>+</e:mo></e:mrow></e:msup><e:msup><e:mrow><e:mi>e</e:mi></e:mrow><e:mrow><e:mo>−</e:mo></e:mrow></e:msup><e:mo stretchy="false">→</e:mo><e:msup><e:mrow><e:mi mathvariant="normal">K</e:mi></e:mrow><e:mrow><e:mo>+</e:mo></e:mrow></e:msup><e:msup><e:mrow><e:mi mathvariant="normal">K</e:mi></e:mrow><e:mrow><e:mo>−</e:mo></e:mrow></e:msup></e:mrow></e:math> process as a narrow resonance and not appearing in the <j:math xmlns:j="http://www.w3.org/1998/Math/MathML" display="inline"><j:mrow><j:msup><j:mrow><j:mi>e</j:mi></j:mrow><j:mrow><j:mo>+</j:mo></j:mrow></j:msup><j:msup><j:mrow><j:mi>e</j:mi></j:mrow><j:mrow><j:mo>−</j:mo></j:mrow></j:msup><j:mo stretchy="false">→</j:mo><j:msup><j:mrow><j:mi>π</j:mi></j:mrow><j:mrow><j:mo>+</j:mo></j:mrow></j:msup><j:msup><j:mrow><j:mi>π</j:mi></j:mrow><j:mrow><j:mo>−</j:mo></j:mrow></j:msup></j:mrow></j:math> process at all.
