“…(6) Formidable precision tests of WEP and the r dependence of forces between matter aggregates are being pursued in recent years. They reached the centimeter to micron scale of distances from different approaches like torsion balance [26,27], optical levitation [28] and atom interferometry [29,30]. When interpreted in terms of a new "fifth force" Yukawa interaction, the present upper limit to its coupling relative to gravity goes [27] from 1 to 10 6 for a corresponding range from 40 to 1 micron.…”

Following these guiding concepts, we have developed [31] the theory of the long-range force mediated by two neutrinos including for the first time all ingredients of neutrino physics relevant to the region of distances near the range of the interaction, with masses, mixing and the Dirac/ Majorana distinction.…”

Absolute neutrino mass and the Dirac/Majorana distinction from the weak interaction of aggregate matter

The 2ν-mediated force has a range of microns, well beyond the atomic scale. The effective potential is built from the t-channel absorptive part of the scattering amplitude and depends on neutrino properties on shell. We demonstrate that neutral aggregate matter has a weak charge and calculate the matrix of six coherent charges for its interaction with definite-mass neutrinos. Near the range of the potential the neutrino pair is nonrelativistic, leading to observable absolute mass and Dirac/Majorana distinction via different r-dependence and violation of the weak equivalence principle.

“…These and other theories involve extra time [139] and space [140] dimensions and new scalar and vector mediators such the axion [141], dilaton [142], dark photon and Z [143], all of which can alter the typical 1/r scaling of the gravitational potential and break the weak equivalence principle. Torsion balance experiments have excluded a region in the |α| − λ parameter space of the Yukawa-type parametrisation of deviations from the 1/r potential [144][145][146][147][148][149][150][151][152]. Other experiments probing macroscopic distances have used optical levitation [153,154] and atom interferometry [155].…”

We investigate forces induced by the exchange of two light neutrinos between Standard Model (SM) fermions in the presence of effective operators parametrising physics beyond the SM. We first set up a general framework in which we derive the long-range potential mediated by weakly interacting neutrinos in the SM, retaining both spin-independent and spin-dependent terms. We then derive neutrino-mediated potentials when there are vector, scalar and tensor non-standard interactions present as well as an exotic neutrino magnetic moment. Examining the phenomenology of such long-range potentials in atomic scale laboratory experiments, we derive upper bounds on the Wilson coefficients of the effective operators and compare these to those from processes such as charged lepton flavour violation.

“…Other experimental parameters are reported in SI units for clarity. While the neutron coupling to light mediators g n is strongly constrained by fifth-force searches and equivalence principle tests [48,49], g d is considerably less constrained. Couplings for which g d ≫ g n are typically required to produce observable signals.…”

Search for Composite Dark Matter with Optically Levitated Sensors

et al. 2020

Results are reported from a search for a class of composite dark matter models with feeble long-range interactions with normal matter. We search for impulses arising from passing dark matter particles by monitoring the mechanical motion of an optically levitated nanogram mass over the course of several days. Assuming such particles constitute the dominant component of dark matter, this search places upper limits on their interaction with neutrons of α n ≤ 1.2 × 10 −7 at 95% confidence for dark matter masses between 1 and 10 TeV and mediator masses m ϕ ≤ 0.1 eV. Because of the large enhancement of the cross section for dark matter to coherently scatter from a nanogram mass (∼10 29 times that for a single neutron) and the ability to detect momentum transfers as small as ∼200 MeV=c, these results provide sensitivity to certain classes of composite dark matter models that substantially exceeds existing searches, including those employing kilogram-or ton-scale targets. Extensions of these techniques can enable directionally sensitive searches for a broad class of previously inaccessible heavy dark matter candidates.
