A search for the decays B-s(0) -> mu(+)mu(-) and B-0 -> mu(+)mu(-) is performed with 0.37 fb(-1) of pp collisions at root s = 7 TeV collected by the LHCb experiment in 2011. The upper limits on the branching fractions are B(B-s(0) -> mu(+)mu(-)) < 1.6 x 10 ...

A measurement of the lifetimes of the Omega(0)(c) and Xi(0)(c) baryons is reported using proton-proton collision data at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb(-1) collected by the LHCb experiment. The Omega( ...

The differential branching fraction of the decay Lambda(0)(b) -> Lambda mu(+) mu(-) is measured as a function of the square of the dimuon invariant mass, q(2). A yield of 78 +/- 12 Lambda(0)(b) -> Lambda mu(+) mu(-) decays is observed using data, correspon ...

We present a measurement of R-K(), the branching fraction ratio B(B -> K mu(+)mu(-))/B(B -> K* e(+) e(-)), for both charged and neutral B mesons. The ratio for the charged case RK*+ is the first measurement ever performed. In addition, we report absolute ...

We report the analysis of the three-body e(+)e(-) -> B (B) over bar pi(+/-), B (B) over barpi(+/-), and B(B) over bar* pi(+/-) processes, including the first observations of the Z(b)(+/-)(10610) -> B (B) over bar* + c.c. and Z(b)(+/-)(10650) -> [B ...

The mass of the τ lepton has been measured in the decay mode τ→3πντ using a pseudomass technique. The result obtained from 414fb-1 of data collected with the Belle detector is Mτ=[1776.61±0. 13(stat)±0.35(sys)]MeV/c2. The upper limit on the relative mass d ...

We measure the branching fractions of B-0 -> J/psi eta((')) decays with the complete Belle data sample of 772 x 10(6) B (B) over bar events collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The result ...

A measurement of the branching fraction of the decay B-s(0) -> (KSKS0)-K-0 is performed using proton- proton - collision data corresponding to an integrated luminosity of 5 fb(-1) collected by the LHCb experiment between 2011 and 2016. The branching fracti ...

The prompt production of the charmonium chi(c1) and chi(c2) mesons has been studied in proton-proton collisions at the Large Hadron Collider at a centre-of-mass energy of root s = 7 TeV. The chi(c) mesons are identified through their decays chi(c) -> J/psi ...

First observations of the decays A(b)(0) -> A(c)(+)D((s))(-) are reported using data corresponding to an integrated luminosity of 3 fb(-1) collected at 7 and 8 TeV center-of- ass energies in proton-proton collisions with the LHCb detector. In addition, the ...

The B+ -> D+K+pi(-) decay is observed in a data sample corresponding to 3.0 fb(-1) of pp collision data recorded by the LHCb experiment during 2011 and 2012. The signal significance is 8 sigma and the branching fraction is measured to be B(B+ -> D+K+pi(-)) ...

The production of B-+/- mesons in proton-proton collisions at root s = 7 TeV is studied using 35 pb(-1) of data collected by the LHCb detector. The B-+/- mesons are reconstructed exclusively in the B-+/- -> J/(sic)K-+/- mode, with J/(sic) -> mu(+)mu(-). Th ...

Violations of CPT symmetry and Lorentz invariance are searched for by studying interference effects in B-0 mixing and in B-s(0) mixing. Samples of B-0 -> J/psi K-S(0) and B-0(s) -> J/psi K+K- decays are recorded by the LHCb detector in proton-proton collis ...

Based on data corresponding to an integrated luminosity of 0.37 fb(-1) collected by the LHCb experiment in 2011, the following ratios of branching fractions are measured: B(B-0 ->pi(+)pi(-))/B(B-0 -> K+pi(-))=0.262 +/- 0.009 +/- 0.017, (f(s)/f(d)).B(B-s(0) ...

The first observations of B-0 -> (D) over bar*(2007)K-0(+)pi(-) and B-s(0) -> (D) over bar*(2007)K-0(-)pi(+) decays are presented, and their branching fractions relative to that of the B ->( D) over bar* (2007)(0)pi(+)pi(-) decay are reported. These modes ...

Bottom baryons decaying to a J/psi meson and a hyperon are reconstructed using 1.0 fb(-1) of data collected in 2011 with the LHCb detector. Significant Lambda(0)(b) -> J/psi Lambda, Xi(-)(b) -> J/psi Xi(-) and Omega(-)(b) -> J/psi Omega(-) signals are obse ...

SND@LHC is a compact and stand-alone experiment designed to perform measurements with neutrinos produced at the LHC in the pseudo-rapidity region of 7.2 < η < 8.4. The experiment is located 480 m downstream of the ATLAS interaction point, in the TI18 tunne ...

A model-independent search for direct CP violation in the Cabibbo-suppressed decay D+ -> K- K+ pi(+) in a sample of approximately 370 000 decays is carried out. The data were collected by the LHCb experiment in 2010 and correspond to an integrated luminosi ...
