Recent Results from BESIII experiment  [PDF]
Liaoyuan Dong,for the BESIII Collaboration
Physics , 2011,
Abstract: We report some recent results on charmonium spectroscopy and hadron spectroscopy from BESIII experiment, including the measurements of the masses and widths of $h_c$, $\eta_c$, $\eta_c(2S)$ and some new resonances around 2 GeV. The results are based on a data sample of 106 million $\psi^\prime$ events and 226 million J/$\psi$ events collected with the BESIII detector at the BEPCII collider.
Recent Results from the MINOS experiment  [PDF]

Abstract: MINOS is an accelerator neutrino oscillation experiment at Fermilab. An intense high energy neutrino beam is produced at Fermilab and sent to a near detector on the Fermilab site and also to a 5 kTon far detector 735 km away in the Soudan mine in northern Minnesota. The experiment has now had several years of running with millions of events in the near detector and hundreds of events recorded in the far detector. I will report on the recent results from this experiment which include precise measurement of $|\Delta m^2_{32}|$, ~analysis of neutral current data to limit the component of sterile neutrinos, and the search for $\nu_\mu \to \nu_e$ conversion. The focus will be on the analysis of data for $\nu_\mu \to \nu_e$ conversion. Using data from an exposure of $3.14\times 10^{20}$ protons on target, we have selected electron type events in both the near and the far detector. The near detector is used to measure the background which is extrapolated to the far detector. We have found 35 events in the signal region with a background expectation of $27\pm 5(stat)\pm 2(syst)$. Using this observation we set a 90% C.L. limit of $\sin^2 2 \theta_{13} < 0.29$ for $\delta_{cp} = 0$ and normal mass hierarchy. Further analysis is under way to reduce backgrounds and improve sensitivity.
Recent Results from the BRAHMS Experiment  [PDF]

Physics , 2005, DOI: 10.1142/S0217751X05027941
Abstract: We present recent results obtained by the BRAHMS experiment at the Relativistic Heavy Ion Collider (RHIC) for the systems of Au + Au and Cu + Cu at \rootsnn{200} and at 62.4 GeV, and p + p at \rootsnn{200}. Nuclear modification factors for Au + Au and Cu + Cu collisions are presented. Analysis of anti-particle to particle ratios as a function of rapidity and collision energy reveal that particle populations at the chemical freeze-out stage for heavy-ion reactions at and above SPS energies are controlled by the baryon chemical potential. From the particle spectra we deduce significant radial expansion ($\beta \approx $ 0.75), as expected for systems created with a large initial energy density. We also measure the elliptic flow parameter $v_2$ versus rapidity and \ptn. We present rapidity dependent $p/\pi$ ratios within $0 < y < 3$ for Au + Au and Cu + Cu at \rootsnn{200}. \Raa is found to increase with decreasing collision energy, decreasing system size, and when going towards more peripheral collisions. However, \Raa shows only a very weak dependence on rapidity (for $0 < y < 3.2$), both for pions and protons.

Abstract: We report the recent results of a search for the decay B- --> tau- anti-nu_tau, observations of new resonances X, Y and Z, and the first results from Upsilon(5S) data collected with the Belle detector at KEKB e+e- collider.
Recent Results from the ZEUS Experiment  [PDF]

Physics , 2004,
Abstract: A summary of recent results from ZEUS is presented. New ZEUS results from HERA-1 data include Structure Functions, QCD fits, analysis of hadronic final states, precision measurements of alpha_s, production of heavy flavor mesons and baryons and studies of diffraction. Results from the new HERA-II running include the measurement of the cross section for polarized charged current events and charm events tagged with the new ZEUS vertex detector.

Physics , 2013,
Abstract: In this talk, we present a selection of recent results from BESIII collaboration, including observation of the charmoniumlike states, Zc(3900), Zc(4020) and Zc(4025); observation of e+e- -> gamma X(3872); partial wave analysis of J/psi -> gamma eta eta; measurement of D+ -> mu+ nu and D0 -> K- e+ nu, pi- e+ nu. The results are based on the data samples collected with the BESIII detector at central-of-mass energies from 3.900 to 4.420 GeV, and at the energies of J/psi and psi(3770) resonances.
Recent Results from the KTeV Experiment  [PDF]
M. J. Wilking
Physics , 2006,
Abstract: We present recent preliminary results from five decay channels. From the $K_L\to\pi^+\pi^-\gamma$ channel, we extract form factors for the CP violating M1 direct photon emission amplitude and the fraction of the total decay amplitude that is due to direct emission. We have placed an upper limit on the $K_L\to\pi^0\pi^0\gamma$ branching ratio, and preliminary measurements of the $K_L\to\pi^{\pm}e^{\mp}\nu e^+e^-$ and $\pi^0\to e^+e^-$ branching ratios are presented. Finally, we report measurements of both the branching ratio and the form factor parameters for the decay $K_L\to e^+e^-\gamma$.

Abstract: The status of dark matter search with the HDMS experiment is reviewed. After one year of running the HDMS prototype detector in the Gran Sasso Underground Laboratory, the inner crystal of the detector has been replaced with a HPGe crystal of enriched 73Ge. The results of the operation of the HDMS prototype detector are discussed.

Abstract: MAXIMA is a balloon-borne platform for measuring the anisotropy of the Cosmic Microwave Background (CMB). It has measured the CMB power spectrum with a ten-arcminute FWHM beam, corresponding to a detection of the power spectrum out to spherical harmonic multipole l~1000. The spectrum is consistent with a flat Universe with a nearly scale-invariant initial spectrum of adiabatic density fluctuations. Moreover, the MAXIMA data are free from any notable non-Gaussian contamination and from foreground dust emission. In the same region, the WMAP experiment observes the same structure as that observed by MAXIMA, as evinced by analysis of both maps and power spectra. The next step in the evolution of the MAXIMA program is MAXIPOL, which will observe the polarization of the CMB with comparable resolution and high sensitivity over a small patch of the sky.
Recent Results from the AMANDA Experiment  [PDF]
Peter Niessen,for the AMANDA collaboration
Physics , 2003,
Abstract: AMANDA (Antarctic Muon And Neutrino Detector Array) is a neutrino telescope built under the southern polar icecap and its scope is to explore the possibility to detect high energy cosmic neutrinos. This should generate insight into the powerful celestial objects where acceleration mechanisms can bring up to $10^{20}$ eV. We describe the achievements and results from the AMANDA-B10 prototype and the preliminary results from the current AMANDA-II detector which show dramatic increase in sensitivity.
