“…There are at least two well motivated ways to couple a new light Z to the SM without affecting the huge phenomenological success of the SM [36][37][38][39][40][41][42][43][44][45]. The first is to couple the new boson via kinetic mixing with the hypercharge vector.…”

If dark matter interacts with quarks or gluons, the mediator of these interactions is either directly accessible at the LHC or is so heavy that its effects are encoded in contact operators. We find that the self-consistency of a contact operator description at the LHC implies bounds on the mediator scale stronger than those found from missing energy searches. This translates into spin-independent elastic scattering cross-sections at a level < ∼ 10 −41 cm 2 , with direct implications for the DAMA, CoGeNT, and CRESST-II anomalies. We then carefully explore the potential of monojet searches in the light mediator limit, focusing on a Z model with arbitrary couplings to quarks and dark matter. We find that Tevatron data currently provides the most stringent bounds for dark matter and Z masses below 100 GeV, and that these searches can constrain models for the DAMA, CoGeNT, and CRESST-II anomalies only if the mediator can decay to a pair of dark matter particles.

“…Additional Higgs and gauge bosons appear in more complex setups [16]. The coupling strength between the SM and the hidden sector, , can naturally be as large as 10 −4 − 10 −2 [15], opening the possibility of probing a light hidden sector at low-energy e + e − colliders. A search for dark photon and associated scalar boson has been performed at BABAR in the range 0.8 < m h < 10.0 GeV and 0.25 < m A < 3.0 GeV, with the constraint m h > 2m A [17] …”

Abstract. Recent BABAR results on several topics are presented. We report the observation of T-violation as well as recent results on CP-violation in B decays in a dataset collected at the Y(4S) resonance. We also present searches for low mass CP-odd Higgs bosons, predicted in non-minimal SUSY models, as well as searches for dark-sector gauge bosons motivated by astrophysical observations, using radiative decays of the Y(1S,2S,3S) resonances and other e + e − processes. These searches enable stringent limits to be set on the parameters of such particles. IntroductionBABAR [1] is a detector optimized for CP Violation (CPV) studies of the B system produced in e + e − by the boosted Υ(4S ) resonance. The data taking at the SLAC PEP-II asymmetric collider started in 2000 and ended in April 2008; a great number of events on the Y resonances was recorded, and many analyses are still going on, producing refinements of previous work or completely new results. The spectrum of BABAR Physics is very wide, having to pick a few topics for this Conference, I chose the measurement of T violation in B 0 decays, which was made possible following an original idea, and some searches for hypothetical particles suggested in many model beyond the Standard Model, as light Higgs or dark matter particles. CP and Time Reversal Violation Data SampleThe CP Violazion (CPV) and the Time Reversal Violation (TRV) analysis make use of the full dataset recorded by the BABAR detector at the PEP-II machine at SLAC . This sample consists of 426 fb −1 integrated luminosity at the Υ(4S ) resonance, corresponding to 468 × 10 6 BB pairs, and 45 fb

“…In a minimal model [44], the dark photon mass is generated via the Higgs mechanism, adding a dark Higgs boson in the theory. The mass hierarchy between dark photon and dark Higgs boson is not constrained experimentally, so the dark Higgs boson could be light as well [45].…”
