Leptonic probes of alternative left-right symmetric models

We explore constraints on the parameter space of the alternative left-right model originating from the leptonic sector. Our analyses focuses on both lepton-flavor-conserving observables, particularly the anomalous magnetic moment of the muon, and lepton-flavor-violating processes like <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mi>μ</a:mi><a:mo stretchy="false">→</a:mo><a:mi>e</a:mi><a:mi>γ</a:mi></a:math> decay and <d:math xmlns:d="http://www.w3.org/1998/Math/MathML" display="inline"><d:mi>μ</d:mi><d:mo>−</d:mo><d:mi>e</d:mi></d:math> conversions in nuclei. While contributions to the anomalous magnetic moment fall below the measured values at <f:math xmlns:f="http://www.w3.org/1998/Math/MathML" display="inline"><f:mrow><f:mn>2</f:mn><f:mi>σ</f:mi></f:mrow></f:math>, current and future experimental sensitivities to flavor-violating branching rations of the Standard Model leptons are expected to impose lower bounds on the mass of the peculiar <h:math xmlns:h="http://www.w3.org/1998/Math/MathML" display="inline"><h:mi>S</h:mi><h:mi>U</h:mi><h:mo stretchy="false">(</h:mo><h:mn>2</h:mn><h:msub><h:mo stretchy="false">)</h:mo><h:mi>R</h:mi></h:msub></h:math> gauge boson of the model. This provides complementary constraints relative to existing limits, which are indirect and derived from collider bounds on the mass of the associated neutral gauge boson <l:math xmlns:l="http://www.w3.org/1998/Math/MathML" display="inline"><l:msup><l:mi>Z</l:mi><l:mo>′</l:mo></l:msup></l:math>.
