J/psi -> gamma+X, where X is a na... | hep-ex |
Observation of the rare decay B+->K+pi0pi0 and measurement of the
quasi-two body contributions B+->K*(892)+pi0, B+->f0(980)K+ and B+->chic0K+: We report an analysis of the charmless hadronic decays of charged B meson to
the final state K+pi0pi0, using a data sample of 470+/-2.8 million BBbar events
collected at the Y... | hep-ex |
Spin Structure Functions g_1 and g_2 for the Proton and Deuteron: The experiment E155 at SLAC measured the spin structure functions g_1 and g_2
of the proton and deuteron. The experiment used deep inelastic scattering of
48.3 GeV longitudinally polarized electrons incident on polarized solid
^{15}NH_3 and ^{6}LiD targe... | hep-ex |
Search for dark matter in events with a leptoquark and missing
transverse momentum in proton-proton collisions at 13 TeV: A search is presented for dark matter in proton-proton collisions at a
center-of-mass energy of $\sqrt{s} =$ 13 TeV using events with at least one
high transverse momentum ($p_\mathrm{T}$) muon, a... | hep-ex |
Measurement of Branching Fractions for $B\to χ_{c1(2)} K (K^*)$ at
Belle: We have measured the branching fractions for the exclusive decay modes $B\to
{\chi}_{c1(2)} K(K^*)$ using a $140~{\rm fb}^{-1}$ data sample collected by the
Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The measured
branching ... | hep-ex |
Search for weakly interacting sub-eV particles with the OSQAR
laser-based experiment: results and perspectives: Recent theoretical and experimental studies highlight the possibility of new
fundamental particle physics beyond the Standard Model that can be probed by
sub-eV energy experiments. The OSQAR photon regenera... | hep-ex |
Results from the first heavy ion run at the LHC: Early November 2010, the LHC collided for the first time heavy ions, Pb on
Pb, at a centre-of-mass energy of 2.76 TeV/nucleon. This date marked both the
end of almost 20 years of preparing for nuclear collisions at the LHC, as well
as the start of a new era in ultra-rela... | hep-ex |
Measurement of the Branching Fractions for Inclusive $B^-$ and $\bar
B^0$ Decays to Flavor-tagged $D$, $D_s$ and $Λ_c$: We report on the inclusive branching fractions of $B^-$ and of ${\bar B}^0$
mesons decaying to ${D^0 X}$, ${{\bar D}^0 X}$, ${D^+ X}$, ${D^- X}$, ${D_s^+
X}$, ${D_s^- X}$, ${\Lambda_c^+ X}$, ${{\bar... | hep-ex |
Analysis of Neutral Current Interactions in MINOS: A Search for Sterile
Neutrinos: A search for disappearance of active neutrinos over a baseline of 735 km was
conducted using the NuMI neutrino beam and the MINOS detectors. The data
analyzed correspond to an exposure of 3.18x10^{20} protons on target. The data
are fi... | hep-ex |
Search for Dimuon Decays of a Light Scalar Boson in Radiative
Transitions Upsilon -> gamma A0: We search for evidence of a light scalar boson in the radiative decays of the
Upsilon(2S) and Upsilon(3S) resonances: Upsilon(2S,3S)-> gamma A0, A0 -> mu^+
mu^-. Such a particle appears in extensions of the Standard Model, ... | hep-ex |
Status and Perspectives of Neutrino Physics: I will first give a brief but comprehensive review of the status of our
knowledge in neutrino physics. With reference to a not too far future I will
then discuss the perspectives that appear to me to be most important and
promising. | hep-ex |
