Pith's verdict: The structural result is real and useful — NUHM1 gives two low-relic-density solutions at any tan beta and m0, NUHM2 opens new co-annihilation regions — but the detection-rate numbers are looser than the abstract implies, and the paper never shows the overlap between its VR>1 contours and the WMAP central band.

The paper

The paper claims

Letting the Higgs soft masses differ from squark masses turns two narrow dark-matter corners into broad, tunable regions, and puts neutralinos within reach of direct detection and a linear collider.

The reading

The paper asks what happens to supersymmetric dark matter when one assumption of the minimal supergravity model is dropped: that the two Higgs fields carry the same soft-breaking mass as the squarks and sleptons at the grand-unified scale. Universality among the matter scalars is kept, because that is what suppresses unwanted flavor-changing processes, but the Higgs masses are allowed to float — one extra parameter in the NUHM1 model ($m_phi$, with $m_{H_u}^2 = m_{H_d}^2 ne m_0^2$) and two in NUHM2. The payoff is that the two narrow corners where the minimal model can satisfy the WMAP cold-dark-matter density — the heavy-Higgs annihilation funnel, reachable only at large $tan beta$, and the higgsino region, reachable only at multi-TeV $m_0$ — become broad regions that can be dialed into at almost any point of the parameter space. If the authors are right, a large family of spectra the minimal model forbids is viable, and several of those spectra put the neutralino within reach of XENON-class direct detection, IceCube, and a 0.5–1 TeV linear collider.

What carries the argument

The argument runs through the renormalization-group evolution of the Higgs soft masses and the two electroweak-symmetry-breaking minimization conditions. The key relation is that a deviation of the Higgs mass from the universal value at the GUT scale survives running with its sign intact but shrinks in magnitude, $Delta m_{H_u}^2(mathrm{weak}) simeq Delta m_{H_u}^2(mathrm{GUT}), e^{-J_t}$ with $J_t = frac{3}{8pi^2} int dt, f_t^2 > 0$, so positive and negative $m_phi$ push $mu$ and $m_A$ in opposite directions through $mu^2 = frac{m_{H_d}^2 - m_{H_u}^2 tan^2beta}{tan^2beta - 1} - frac{M_Z^2}{2}$ and $m_A^2 = m_{H_u}^2 + m_{H_d}^2 + 2mu^2$. In NUHM2 a nonzero $S = m_{H_u}^2 - m_{H_d}^2$ enters the third-generation and first-generation scalar RGEs with hypercharge-weighted signs, splitting squark and slepton masses within a generation. The phenomenological filter is a $chi^2$ over three measurements — $Omega_{mathrm{CDM}} h^2 = 0.113 pm 0.009$, $BF(b to sgamma) = (3.25 pm 0.37) times 10^{-4}$ and $Delta a_mu = (27 pm 10) times 10^{-10}$ — plus the LEP2 chargino bound $m_{tilde W_1} geq 103.5$ GeV, with spectra from Isajet, relic densities from IsaReD and detection rates from DarkSUSY. Detection prospects are expressed as visibility ratios, signal over projected sensitivity, computed for two self-consistent halo models (a cored Burkert profile and an adiabatically contracted N03 profile) so that direct and indirect channels are compared on the same footing.

Extended reading notes

Core claim

The central claim is that splitting the GUT-scale Higgs soft masses from the matter-scalar mass $m_0$ changes which supersymmetric spectra are compatible with the measured relic density, and changes them in a way that is observable. In NUHM1 the authors argue that for essentially any choice of $m_0$, $m_{1/2}$ and $tan beta$ there are two values of $m_phi$ that bring $Omega_{tilde Z_1} h^2$ into the WMAP range: a large negative $m_phi$ pushes the pseudoscalar mass $m_A$ down to roughly twice the neutralino mass, opening the A-annihilation funnel at any $tan beta$ including low values; a large positive $m_phi$ drives $m_{H_u}^2$ negative faster during running, so that $|mu|$ becomes small while $m_0$ stays low, giving a higgsino-like lightest neutralino without the multi-TeV scalars of the minimal model's focus point. In NUHM2, $mu$ and $m_A$ can be taken as weak-scale inputs, so either region is reachable by choice for any $m_0$, $m_{1/2}$ and $tan beta$ that yields a valid spectrum. The paper further identifies co-annihilation regions that exist only in NUHM2: a large positive $S = m_{H_u}^2 - m_{H_d}^2$ drives the right-handed up and charm squarks very light, and a large negative $S$ makes the left sleptons and sneutrinos light, both of which suppress the relic density and, in the squark case, strongly enhance the spin-independent neutralino-proton cross section.

Load-bearing premise

The detection-rate claims assume that the neutralino makes up the full local dark matter density even at parameter points whose computed thermal relic abundance falls short of the measured value; the authors state this explicitly in Sec. 2.4, where they do not rescale the visibility ratios downward, and footnote 1 invokes unspecified non-thermal production or a cosmological enhancement to make up the difference.

Editorial extensions

If this is right

  • The relic-density constraint stops being a filter that forces either large $tan beta$ or multi-TeV scalar masses; spectra with low $tan beta$ and low $m_0$ become viable, so the WMAP measurement alone no longer points to a particular corner of the supersymmetric parameter space.
  • In the low-$mu$ higgsino region, charginos and neutralinos are light enough that a $sqrt{s} = 0.5$–1 TeV linear collider can reach beyond the LHC, because the LHC reach is set by squark and gluino masses while the collider reach is set by $mu$.
  • In the A-funnel region, $H$, $A$ and $H^pm$ can be light enough for direct production at the LHC or a linear collider, and can appear in gluino and squark cascades, at values of $tan beta$ far below where the minimal model allows this.
  • In NUHM2, very light $tilde u_R$ and $tilde c_R$ squarks or light left sleptons can supply the needed co-annihilation, giving large spin-independent direct detection rates and, for the squarks, dijet plus missing-energy signals at hadron colliders.
  • The same relic density can be reproduced by spectra with very different collider signatures, so a measurement of the dark matter density alone does not determine what the LHC or a linear collider will see.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • If the thermal relic abundance is later shown to saturate the cosmic density with no non-thermal component, the parameter regions where $Omega h^2$ falls below about 0.094 would be removed, and with them much of the funnel and higgsino parameter space used here to argue for observable rates.
  • The NUHM2 squark co-annihilation window makes the spin-independent cross section a sharp function of the Higgs mass splitting, so a null result from a ton-scale direct detection experiment would translate into a constraint on $S$ at the GUT scale rather than merely on $m_0$ and $m_{1/2}$.
  • Because the funnel can open at low $tan beta$, the usual expectation that cascade decays are tau-rich in funnel points does not carry over, which changes the event selection that collider searches should optimize for dark-matter-motivated spectra.
  • The two-parameter version effectively promotes $mu$ and $m_A$ to inputs, so any future measurement of a light Higgsino and a heavy pseudoscalar (or the reverse) would already discriminate NUHM2 from the one-parameter case without a full spectrum fit.
Original abstract

In supersymmetric models with gravity-mediated SUSY breaking, universality of soft SUSY breaking sfermion masses m_0 is motivated by the need to suppress unwanted flavor changing processes. The same motivation, however, does not apply to soft breaking Higgs masses, which may in general have independent masses from matter scalars at the GUT scale. We explore phenomenological implications of both the one-parameter and two-parameter non-universal Higgs mass models (NUHM1 and NUHM2), and examine the parameter ranges compatible with Omega_CDM h^2, BF(b --> s,gamma) and (g-2)_mu constraints. In contrast to the mSUGRA model, in both NUHM1 and NUHM2 models, the dark matter A-annihilation funnel can be reached at low values of tan(beta), while the higgsino dark matter annihilation regions can be reached for low values of m_0. We show that there may be observable rates for indirect and direct detection of neutralino cold dark matter in phenomenologically aceptable ranges of parameter space. We also examine implications of the NUHM models for the Fermilab Tevatron, the CERN LHC and a Sqrt(s)=0.5-1 TeV e+e- linear collider. Novel possibilities include: very light s-top_R, s-charm_R squark and slepton_L masses as well as light charginos and neutralinos and H, A and H^+/- Higgs bosons.

Thus, we see that in the case of large negative mφ values, we would expect a large |µ| parameter, whereas for large positive mφ values, m2 Hu is barely driven to negative values, and we expect a small |µ| parameter.

Thus, when Xt is small (for mφ < m0), the diagonal entries in the top and bottom squark mass squared matrices are not as suppressed due to top Yukawa coupling effects as in the mSUGRA case. In contrast, for large positive values of mφ, Xt is large and these soft masses are more suppressed resulting lighter third generation squarks. These expectations are indeed born out in
