“…More relevant in the present context are the constraints obtained from supernova SN1987A [35] or the metallicity of red giant stars [36], which limit axion-nucleon interactions. The 14.4 keV emission line of 57 Fe also constrains axionnucleon couplings [37]. However, these astrophysical constraints are somewhat particular to the axion, and do not apply to other pseudoscalar bosons or axial-vector interactions [9,38].…”

A comparison between existing nuclear magnetic resonance measurements and calculations of the scalar spin-spin interaction (J-coupling) in deuterated molecular hydrogen (HD) yields stringent constraints on anomalous spin-dependent potentials between nucleons at the atomic scale (∼ 1Å). The dimensionless coupling constant g p P g N P /4π associated with exchange of pseudoscalar (axion-like) bosons between nucleons is constrained to be less than 5 × 10 −7 for boson masses in the range of 5 keV, representing improvement by a factor of 100 over previous constraints. The dimensionless coupling constant g −19 for bosons of mass < ∼ 1000 eV, improving constraints at this distance scale by a factor of 100 for proton-proton couplings and more than 8 orders of magnitude for neutron-proton couplings.PACS numbers: 14.80. Va, 11.40.Ha, Over the past few decades, searches for anomalous spin-dependent forces have drawn considerable interest as a signature of the axion [1], a hypothetical pseudoscalar Goldstone boson [2,3] arising out of the Peccei-Quinn solution to the strong-CP problem [4,5]. Axions are also appealing as a candidate for dark matter [6]. Other exotic spin-dependent interactions are predicted by a variety of novel theories such as those involving para-photons [7] and unparticles [8].The possible spin-dependent forces that could arise from exchange of scalar/pseudoscalar or vector gauge bosons are enumerated in Ref. [9]. Another theoretical framework for considering anomalous spin-dependent interactions comes from introducing nonzero torsion into general relativity, which causes gravity to acquire scalar and vector components that manifest as new spin-mass and spin-spin couplings [10][11][12][13]. Spontaneous Lorentz violation may also generate exotic spindependent interactions [14].Recent experiments have significantly improved constraints on long-range (tens of cm) dipole-dipole interactions between neutrons [15, 16] and monopole-dipole interactions between electrons and nucleons [17]. Earlier work constrained monopole-dipole interactions between nuclei [18] and anomalous dipole-dipole interactions between electrons [19,20] and electrons and nuclei [21]. Constraints on new pseudoscalar interactions can also be obtained from spin-independent tests of the inverse square law [22]. Other laboratory experiments constrain anomalous monopole-dipole couplings on length scales in the range of µm to mm [23][24][25][26]. Spin relaxation studies of hyperpolarized 3 He gas have been used to limit anomalous dipole-dipole interactions between neutrons at length scales of about 100 nm [27]. Because of the possibility that new force-mediating bosons may be massive and have limited range, it is of considerable interest to find experimental techniques to search for anomalous spin-dependent interactions at even shorter distances.Here we discuss constraints on the existence of anomalous dipole-dipole forces on angstrom length scales. Our constraints are obtained by comparison of nuclear magnetic resonance (NMR) measurements and th...

The search for solar axions produced by Compton ( þ e À ! e À þ A) and bremsstrahlunglike (e À þ Z ! Z þ e À þ A) processes has been performed. The axion flux in both cases depends on the axionelectron coupling constant. The resonant excitation of the low-lying nuclear level of 169 Tm was looked for: A þ 169 Tm ! 169 Tm Ã ! 169 Tm þ (8.41 keV). The Si(Li) detector and 169 Tm target installed inside the low-background setup were used to detect 8.41 keV rays. As a result, a new model-independent restriction on the axion-electron and the axion-nucleon couplings was obtained: g Ae Â jg 0 AN þ g 3 AN j 2:1 Â 10 À14 . In the model of the hadronic axion this restriction corresponds to the upper limit on the axion-electron coupling and on the axion mass g Ae Â m A 3:1 Â 10 À7 eV (90% C.L.). The limits on the axion mass are m A 105 eV and m A 1:3 keV for the Dine-Fischler-Srednicki-Zhitnitskii-and Kim-Shifman-Vainstein-Zakharov-axion models, correspondingly (90% C.L.).

“…As discussed in Sec. I, within the model of hadronic axions, whose coupling constant is a function of m a , the upper limits for the axion mass m a ≤ 159 eV [20] and m a ≤ 145 eV [21] were obtained using the detector of γ-quanta appearing in the deexcitation of the nuclear level excited by solar axions. The parameters of hadronic axions were also found from the neutrino data of supernova SN 1987A [22] and from astrophysical arguments connected with stellar cooling by the axion emission [23,24].…”

“…These interactions are used for experimental searches of axion-like particles in both the laboratory experiments (see below) and in astrophysics (see, for instance, constraints on the axion-photon and axionelectron coupling constants obtained by means of axion solar telescope [17] and from the Compton process and electron-positron annihilation with an axion emission in stellar plasmas [18,19], respectively). Both the laboratory and astrophysical constraints may depend on the model of axions used containing different relations between couplings to different particles (for instance, the constraints from the solar axion data [20,21] and from the neutrino data of supernova SN 1987A [22] are found using the model of hadronic axions, where the coupling constant is a function of the axion mass). The astrophysical constraints may also depend on complicated behavior of matter in stars.…”

Constraints on axion-nucleon coupling constants from measuring the Casimir force between corrugated surfaces

2014

View full text Add to dashboard Cite

We obtain stronger laboratory constraints on the coupling constants of axion-like particles to nucleons from measurements of the normal and lateral Casimir forces between sinusoidally corrugated surfaces of a sphere and a plate. For this purpose, the normal and lateral additional force arising in the experimental configurations due to two-axion exchange between protons and neutrons are calculated. Our constraints following from measurements of the normal and lateral Casimir forces are stronger than the laboratory constraints reported so far for masses of axion-like particles larger than 11 eV and 8 eV, respectively. A comparison between various laboratory constraints on the coupling constants of axion-like particles to nucleons obtained from the magnetometer measurements, Eötvos-and Cavendish-type experiments, and from the Casimir effect is performed over the wide range of masses of axion-like particles from 10 −10 eV to 20 eV.
