Using a variety of measurements, we constrain the mass of this scalar and its couplings to the electron, muon, neutron, and proton. Making no assumptions about the underlying model, these constraints and the requirement that it solve both problems limit the mass of the scalar to between about 100 keV and 100 MeV. We identify two unexplored regions in the coupling constant-mass plane. Potential future experiments and their implications for theories with mass-weighted lepton couplings are discussed.</span></p><p style="margin: 0px;" data-mce-style="margin: 0px;"><span style="font-size: 14.0pt; line-height: 107%;" data-mce-style="font-size: 14.0pt; line-height: 107%;"> </span></p><p style="text-align: center; margin: 0px;" data-mce-style="text-align: center; margin: 0px;"><strong><span style="font-size: 18.0pt; line-height: 107%; font-family: 'Times New Roman',serif;" data-mce-style="font-size: 18.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Wednesday, June 7, 2017</span></strong></p><p style="text-align: center; margin: 0px;" data-mce-style="text-align: center; margin: 0px;"><strong><span style="font-size: 18.0pt; line-height: 107%; font-family: 'Times New Roman',serif;" data-mce-style="font-size: 18.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">4:00pm</span></strong></p><p style="text-align: center; margin: 0px;" data-mce-style="text-align: center; margin: 0px;"><strong><span style="font-size: 18.0pt; line-height: 107%; font-family: 'Times New Roman',serif;" data-mce-style="font-size: 18.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">CEBAF Auditorium</span></strong></p><p style="text-align: center; margin: 0px;" data-mce-style="text-align: center; margin: 0px;"><span style="font-size: 14.0pt; line-height: 107%;" data-mce-style="font-size: 14.0pt; line-height: 107%;"> </span></p></div><div><br></div><div data-marker="__SIG_POST__">-- <br></div><div>Stephanie Tysor<br>Hall A Administrative Assistant<br>Thomas Jefferson National Accelerator Facility<br>(office)757-269-6005 (fax)757-269-5235</div></div></body></html>
