Description
Summary:A fivefold tighter limit follows if composition-dependent interactions are restricted to vector forces. Our galactic-source results test the UFF for ordinary matter attracted toward dark matter, yielding [eta][sup DM](Be,Cu)=([minus]1.3[plus minus]0.9)[times]10[sup [minus]3], [eta][sup DM](Be,Al)=(+1.8[plus minus]1.4)[times]10[sup [minus]3], and [eta][sup DM](Si/Al,Cu)=(+0.7 [plus minus]1.0)[times]10[sup [minus]3]. This provides laboratory confirmation of the usual assumption that gravity is the dominant long-range interaction between dark and luminous matter. We also test Weber's claim that solar neutrinos scatter coherently from single crystals with cross sections [similar to]10[sup 23] times larger than the generally accepted value and rule out the existence of such cross sections.
