Current limit on the dark matter relic abundance may suggest that |μ|<br />should be smaller than prediction in the minimal supergravity scenario (mSUGRA)<br />for moderate <i>ｍ</i><small>0</small> and <i>ｍ<small>1/2</small></i>. The electroweak-ino parameter <i>M<small>1</small>, M<small>2</small></i> and |μ| are<br />then much closer to each other. This can be realized naturally in the non-universal<br />Higgs mass model (NUHM). Since the heaviest neutralino(<i>X</i><small>4</small><sup>～0</sup>) and chargino <br /><i>X</i><small>2</small><sup>～±</sup>) have significant gaugino components, they may appear frequently in the left-<br />handed squark decay and then be detectable at the LHC. In such a case, we<br />showed that the hierarchy of <i>M<small>1</small>, M<small>2</small></i> and |μ| can be determined. In the light<br />slepton mass scenario with non-vanishing lepton-flavor violation (LFV) in the<br />right-handed sector, NUHM with small |μ| corresponds to region of parameter<br />space where strong cancellation among leading contributions to <i>Br(μ→ eγ)</i> can<br />occur. We showed that determination of electroweak-ino hierarchy plays a cru-<br />cial role in resolving cancellation point of <i>Br(μ → eγ)</i> and determination of LFV<br />parameters. We also discussed test of the universality of the slepton masses at<br />the LHC and the implications to SUSY flavor models. |
