A search of axions produced in nuclear transitions was performed at the Kuo-Sheng Nuclear Power Station with a high-purity germanium detector of mass 1.06 kg at a distance of 28 m from the 2.9 GW reactor core. The expected experimental signatures were monoenergetic lines produced by their Primakoff or Compton conversions at the detector. Based on 459.0/96.3 days of reactor ON/OFF data, no evidence of axion emissions were observed and constraints on the couplings g(a gamma gamma) and g(aee) versus axion mass m(a) within the framework of invisible axion models were placed. The KSVZ and DFSZ models can be excluded for 10(4) eV less than or similar to m(a)less than or similar to 10(6) eV. Model-independent constraints on g(a gamma gamma)center dot g(aNN)(1)< 7.7x10(-9) GeV-2 for m(a)less than or similar to 10(5) eV and g(aee)center dot g(aNN)(1)< 1.3x10(-10) for m(a)less than or similar to 10(6) eV at 90% confidence level were derived. This experimental approach provides a unique probe for axion mass at the keV-MeV range not accessible to the other techniques.

Search for heavy long-lived charged particles with the ATLAS detector in pp collisions at root s=7 TeV Aad, G.; et. al. (Elsevier BV, 2011-09-20) A search for long-lived charged particles reaching the muon spectrometer is performed using a data sample of 37 pb(-1) from pp collisions at root s = 7 TeV collected by the ATLAS detector at the LHC in 2010. No excess is observed above the estimated background. Stable (tau) over bar sleptons are excluded at 95% CL up to a mass of 136 GeV, in GMSB models with N-5 = 3 , m(messenger) = 250 TeV, sign(mu) = 1 and tan beta = 5. Electroweak production of sleptons is excluded up to a mass of 110 GeV. Gluino R-hadro...
Search for displaced muonic lepton jets from light Higgs boson decay in proton-proton collisions at root s=7 TeV with the ATLAS detector Aad, G.; et. al. (Elsevier BV, 2013-04-10) A search is performed for collimated muon pairs displaced from the primary vertex produced in the decay of long-lived neutral particles in proton-proton collisions at root s = 7 TeV centre-of-mass energy, with the ATLAS detector at the LHC. In a 1.9 fb(-1) event sample collected during 2011, the observed data are consistent with the Standard Model background expectations. Limits on the product of the production cross section and the branching ratio of a Higgs boson decaying to hidden-sector neutral long-liv...
Search for the Standard Model Higgs boson in the two photon decay channel with the ATLAS detector at the LHC Aad, G.; et. al. (Elsevier BV, 2011-11-24) A search for the Standard Model Higgs boson in the two photon decay channel is reported, using 1.08 fb(-1) of proton-proton collision data at a centre-of-mass energy of 7 TeV recorded by the ATLAS detector. No significant excess is observed in the investigated mass range of 110-150 GeV. Upper limits on the cross-section,times branching ratio of between 2.0 and 5.8 times the Standard Model prediction are derived for this mass range. (C) 2011 CERN. Published by Elsevier B.V.

Search for top quark partners with charge 5/3 in the same-sign dilepton and single-lepton final states in proton-proton collisions at root s=13 TeV Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2019-03-01) A search for the pair production of heavy fermionic partners of the top quark with charge 5/3 (X-5/3) is performed in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector at the CERN LHC. The data sample analyzed corresponds to an integrated luminosity of 35.9 fb(-1). The X-5/3 quark is assumed always to decay into a top quark and a W boson. Both the right-handed and left-handed X-5/3 couplings to the W boson are considered. Final states with either a pair of same-sign leptons...
Search for microscopic black hole signatures at the Large Hadron Collider Khachatryan, V.; et. al. (Elsevier BV, 2011-03-01) A search for microscopic black hole production and decay in pp collisions at a center-of-mass energy of 7 TeV has been conducted by the CMS Collaboration at the LHC, using a data sample corresponding to an integrated luminosity of 35 pb(-1). Events with large total transverse energy are analyzed for the presence of multiple high-energy jets, leptons, and photons, typical of a signal expected from a microscopic black hole. Good agreement with the standard model backgrounds, dominated by QCD multijet producti...
