${{\widetilde{\mathit \chi}}_{{1}}^{0}}-{{\mathit p}}$ elastic cross section

Experimental results on the ${{\widetilde{\mathit \chi}}_{{1}}^{0}}-{{\mathit p}}$ elastic cross section are evaluated at ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$=100 GeV. The experimental results on the cross section are often mass dependent. Therefore, the mass and cross section results are also given where the limit is strongest, when appropriate. Results are quoted separately for spin-dependent interactions (based on an effective 4-Fermi Lagrangian of the form ${{\overline{\mathit \chi}}}\gamma {}^{\mu }\gamma {}^{5}\chi {{\overline{\mathit q}}}\gamma _{\mu }\gamma {}^{5}{{\mathit q}}$) and spin-independent interactions (${{\overline{\mathit \chi}}}\chi $ ${{\overline{\mathit q}}}{{\mathit q}}$ ). For calculational details see GRIEST 1988B, ELLIS 1988D, BARBIERI 1989C, DREES 1993B, ARNOWITT 1996 , BERGSTROM 1996 , and BAER 1997 in addition to the theory papers listed in the Tables. For a description of the theoretical assumptions and experimental techniques underlying most of the listed papers, see the review on ``Dark matter'' in this ``Review of Particle Physics,'' and references therein. Most of the following papers use galactic halo and nuclear interaction assumptions from (LEWIN 1996 ).

1  The strongest limit is $2.9 \times 10^{-3}$ pb at ${\mathit m}_{{{\mathit \chi}}}$ = 33 GeV. The limit for scattering on neutrons is $2 \times 10^{-4}$ pb at 100 GeV and is $9.4 \times 10^{-5}$ pb at 33 GeV.
2  The strongest limit is $5 \times 10^{-4}$ pb at ${\mathit m}_{{{\mathit \chi}}}$ = 80 GeV.
3  The strongest limit is $6.5 \times 10^{-4}$ pb at ${\mathit m}_{{{\mathit \chi}}}$ = 30 GeV. This updates AMOLE 2015 .
4  The strongest limit is $5.2 \times 10^{-3}$ pb at 50 GeV. The limit for scattering on neutrons is $2.8 \times 10^{-4}$ pb at 100 GeV and the strongest limit is $2.0 \times 10^{-4}$ pb at 50 GeV. This updates APRILE 2013 .
5  The strongest limit is 0.0043 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}$ = 35 GeV. FELIZARDO 2014 also presents limits for the scattering on neutrons. At ${\mathit m}_{{{\mathit \chi}}}$ = 100 GeV, the upper limit is 0.13 pb and the strongest limit is 0.066 pb at ${\mathit m}_{{{\mathit \chi}}}$ = 35 GeV.
6  This result updates LEBEDENKO 2009A. The strongest limit is $8 \times 10^{-3}$ pb at ${\mathit m}_{{{\mathit \chi}}}$ = 50 GeV. Limit applies to the neutralino neutron elastic cross section.
7  This result updates ARCHAMBAULT 2009 . The strongest limit is 0.032 pb at ${\mathit m}_{{{\mathit \chi}}}$ = 20 GeV.
8  The strongest limit is $6 \times 10^{-3}$ at ${\mathit m}_{{{\mathit \chi}}}$ = 60 GeV.
9  The strongest limit is 1.8 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}$ = 100 GeV.
10  The strongest limit is $5.7 \times 10^{-3}$ at ${\mathit m}_{{{\mathit \chi}}}$ = 35 GeV.
11  This result updates LEE 2007A. The strongest limit is at ${\mathit m}_{{{\mathit \chi}}}$ = 80 GeV.
12  Predictions for the spin-dependent elastic cross section based on a frequentist approach to electroweak observables in the framework of ${{\mathit N}}$ = 1 supergravity models with radiative breaking of the electroweak gauge symmetry.
13  The strongest limit is 0.6 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}$= 30 GeV. The limit for scattering on neutrons is 0.01 pb at ${\mathit m}_{{{\mathit \chi}}}$= 100 GeV, and the strongest limit is 0.0045 pb at ${\mathit m}_{{{\mathit \chi}}}$= 30$~$GeV.
14  Limit applies to neutron elastic cross section.
15  The strongest upper limit is 0.25 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}\simeq{}$40 GeV.
16  The strongest upper limit is 4 pb and occurs at ${{\mathit m}_{{\chi}}}$ $\simeq{}$ 60 GeV. The limit on the neutron spin-dependent elastic cross section is 0.07 pb. This latter limit is improved in AHMED 2009 , where a limit of 0.02 pb is obtained at ${\mathit m}_{{{\mathit \chi}}}$ = 100 GeV. The strongest limit in AHMED 2009 is 0.018 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}$ = 60 GeV.
17  The strongest upper limit is 1.2 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}$ $\simeq{}$ 40 GeV. The limit on the neutron spin-dependent cross section is 35 pb.
18  The strongest upper limit is 0.35 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}$ $\simeq{}$ 60 GeV.
19  The strongest upper limit is 1.2 pb and occurs ${\mathit m}_{{{\mathit \chi}}}$ $\simeq{}$ 30 GeV.
20  ELLIS 2004 calculates the ${{\mathit \chi}}{{\mathit p}}$ elastic scattering cross section in the framework of $\mathit N$=1 supergravity models with radiative breaking of the electroweak gauge symmetry, but without universal scalar masses. In the case of universal squark and slepton masses, but non-universal Higgs masses, the limit becomes $2 \times 10^{-4}$, see ELLIS 2003E.
21  The strongest upper limit is 0.75 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}\approx{}$70 GeV.
22  The strongest upper limit is 30 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}$ $\approx{}$ 20~GeV.
23  The strongest upper limit is 8 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}\simeq{}$30 GeV.
24  ELLIS 2001C calculates the ${{\mathit \chi}}-{{\mathit p}}$ elastic scattering cross section in the framework of $\mathit N$=1 supergravity models with radiative breaking of the electroweak gauge symmetry. In models with nonuniversal Higgs masses, the upper limit to the cross section is $6 \times 10^{-4}$.
25  The strongest upper limit is 3 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}\simeq{}$60 GeV. The limits are for inelastic scattering ${{\mathit X}^{0}}$ ${+}$ ${}^{129}\mathrm {Xe}$ $\rightarrow$ ${{\mathit X}^{0}}{+}$ ${}^{129}\mathrm {Xe}^{*}$ (39.58 keV).
26  The strongest upper limit is 4.4 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}\simeq{}$60 GeV.
27  The strongest upper limit is about 35 pb and occurs at ${\mathit m}_{{{\mathit \chi}}}\simeq{}$15 GeV.
