all-hadronic final state using data collected at a center-of-mass energy of
$\sqrt{\rm{s}}=13$ TeV with the CMS experiment at the CERN LHC. ... | hep-ex |
Experimental Prospects for CP and T Violation Studies in Charm: We present the current status of experimental results and prospects for the
determination of CP and T violation in the charm sector. Such measurements have
acquired renewed interest in recent years in view of theoretical work, which
has highlighted the pos... | hep-ex |
Electroweak penguin decays at LHCb: Promising ways to search for New Physics effects in radiative penguin decays
are in the angular analysis of $B_{d} \rightarrow K^{*0} \mu^{+}\mu^{-}$, in
the measurement of direct CP violation in $\B_{d} \rightarrow
K^{*0}\mu^{+}\mu^{-}$ and a time dependent analysis of $B_{s} \right... | hep-ex |
Recent results on nucleon resonance electrocouplings from the studies of
$π^{+}π^{-}p$ electroproduction with the CLAS detector: Recent results on nucleon resonance studies in $\pi^{+}\pi^{-}p$ electro-
production off protons with the CLAS detector are presented. The analysis of
CLAS data allowed us to determine all ... | hep-ex |
Measurement of Branching Fractions for B->ππ, Kπand KK Decays: We report measurements of the branching fractions for $B^0\to\pi^+\pi^-$,
$K^+\pi^-$, $K^+K^-$ and $K^0\pi^0$, and $B^+\to\pi^+\pi^0$, $K^+\pi^0$,
$K^0\pi^+$ and $K^+\bar{K}{}^0$. The results are based on 10.4 fb$^{-1}$ of
data collected on the $\Upsilon$(4... | hep-ex |
Measurement of B(Y(nS) -> mu+ mu-) at CLEO: The decay branching fractions of the three narrow Upsilon resonances to mu+
mu- have been measured by analyzing about 4.3 1/fb e+e- data collected with the
CLEO III detector. The branching fraction B(Y(1S) -> mu+ mu-) = (2.49 +- 0.02
+- 0.07)% is consistent with the current w... | hep-ex |
Time-dependent CP asymmetries in Bs decays at LHCb: The LHCb experiment will search for New Physics in Bs mixing. The Bs mixing
phase will be extracted from the measurement of the time-dependent CP asymmetry
in exclusive Bs decays governed by the b -> ccbar s quark-level transition.
Large New Physics effects can be dis... | hep-ex |
Study of Upsilon(3S,2S) -> eta Upsilon(1S) and Upsilon(3S,2S) -> pi+pi-
Upsilon(1S) hadronic trasitions: We study the Upsilon(3S,2S)->eta Upsilon(1S) and Upsilon(3S,2S)->pi+pi-
Upsilon(1S) transitions with 122 million Upsilon(3S) and 100 million
Upsilon(2S) mesons collected by the BaBar detector at the PEP-II asymmet... | hep-ex |
Event Structure and Double Helicity Asymmetry in Jet Production from
Polarized p+p Collisions at sqrt(s) = 200 GeV: We report on event structure and double helicity asymmetry ($A_LL$) of jet
production in longitudinally polarized p+p collisions at $\sqrt{s}$=200 GeV.
Photons and charged particles were measured at mid... | hep-ex |
The Status and Prospects of the Muon $g-2$ Experiment at Fermilab: The E989 Muon $g-2$ Experiment at Fermilab aims to measure the muon magnetic
anomaly, $a_\mu$, to an unprecedented precision of 140 parts per billion (ppb),
representing a four-fold improvement over the current best measurement,
achieved at Brookhaven N... | hep-ex |
Measurement of Event Shapes in Proton-Antiproton Collisions at
Center-of-Mass Energy 1.96 TeV: A study of event shape observables in proton-antiproton collisions at 1.96
TeV is presented. The data for this analysis were recorded by the CDF II
detector at the Tevatron collider. The variables studied are the transverse... | hep-ex |
Hunting for Axionlike Dark Matter by Searching for an Oscillating
