Search for the lepton-flavor-violating decays Bs0→e±μ∓ and B0→e±μ∓
A search for the lepton-flavor-violating decays Bs0→e±μ∓ and B0→e±μ∓ is performed with a data sample, corresponding to an integrated luminosity of 1.0 fb-1 of pp collisions at √s=7 TeV, collected by the LHCb experiment. The observed number of Bs0→e±μ∓ and B0→e±μ∓ candidates is consistent with background expectations. Upper limits on the branching fractions of both decays are determined to be B(Bs0→e±μ∓)101 TeV/c2 and MLQ(B0→e±μ∓)>126 TeV/c2 at 95% C.L., and are a factor of 2 higher than the previous bounds

Measurement of in with decays by a combined time-dependent Dalitz plot analysis of BaBar and Belle data
We report measurements of and from a
time-dependent Dalitz plot analysis of with decays, where the light unflavored and neutral
hadron is a , , or meson. The analysis is
performed with a combination of the final data sets of the \babar\ and Belle
experiments containing and
pairs collected at the resonance at the
asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. We
measure and . The result for the direct
measurement of the angle is . The last quoted
uncertainties are due to the composition of the decay amplitude model, which is newly established by a Dalitz plot
amplitude analysis of a high-statistics data sample
as part of this analysis. We find the first evidence for at the
level of standard deviations. The measurement excludes the trigonometric
multifold solution at the level of
standard deviations and therefore resolves an ambiguity in the
determination of the apex of the CKM Unitarity Triangle. The hypothesis of
is ruled out at the level of standard deviations, and
thus CP violation is observed in decays.Comment: To be submitted to Physical Review
It’s Not Only Rents: Explaining the Persistence and Change of Neopatrimonialism in Indonesia
Measurement of the very rare decay
The decay K+→π+νν¯
, with a very precisely predicted branching ratio of less than 10−10
,
is among the best processes to reveal indirect effects of new physics.
The NA62 experiment at CERN SPS is designed to study the K+→π+νν¯
decay and to measure its branching ratio using a decay-in-flight technique.
NA62 took data in 2016, 2017 and 2018, reaching the sensitivity of the Standard Model
for the K+→π+νν¯
decay by the analysis of the 2016 and 2017 data,
and providing the most precise measurement of the branching ratio to date
by the analysis of the 2018 data.
This measurement is also used to set limits on BR(K+→π+X
), where X
is a scalar
or pseudo-scalar particle.
The final result of the BR(K+→π+νν¯
) measurement and its interpretation in terms
of the K+→π+X
decay from the analysis of the full 2016-2018 data set is presented, and future plans and prospects are reviewed

Debate on Federal Philippines: A Citizen\u27s Handbook
This book will surely enrich the public debate on federalism. It will provide the Filipinos with needed data on how the Federal System once embedded into our Constitution would benefit our people.

We of the Ateneo de Manila University, through our School of Government, are glad to make this contribution to the ongoing conversation about federalism in the Philippines. It is our hope that this simple Q & A will empower more Filipinos to engage themselves in this vital issue.
