Measurement of the mass difference m(D-s(+))-m(D+) at CDF II
No full textWe present a measurement of the mass difference m(D-s(+))-m(D+), where both the D-s(+) and D+ are reconstructed in the phipi(+) decay channel. This measurement uses 11.6 pb(-1) of data collected by CDF II using the new displaced-track trigger. The mass difference is found to be m(D-s(+))-m(D+)=99.41+/-0.38(stat)+/-0.21(syst) MeV/c(2)

Experimental determination of the differential cross section for the reaction d(p,2p)n
No full textA kinematically complete experiment for the reaction d(p,2p)n has been performed for an incident proton energy of 28.61 MeV. Simultaneous detection of the two protons was made by two systems of 96 scintillation detectors each (9216 detector pairs), located uniformly over a 1.22 m diameter spherical scattering chamber. Use of an IBM 7094 computer for on-line data acquisition allowed accumulation of approximately 300,000 three-nucleon break-up events during an eight hour period. The differential cross section as a function of the proton center-of-momentum energies and the total break-up cross section are presented. Comparison of the total break-up cross section with a value suggested by other experiments shows fairly good agreement

Precision measurement of D meson mass differences
No full textUsing three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D 0 mass. The measurements are based on a dataset corresponding to an integrated luminosity of 1.0 fb−1 collected in pp collisions at 7 TeV. Using the decay D 0 → K + K − K − π +, the D 0 mass is measured to be M(D0)=1864.75±0.15(stat)±0.11(syst)MeV/c2.
The mass differences
M(D+)−M(D0)=4.76±0.12(stat)±0.07(syst)MeV/c2,M(Ds)−M(D+)=98.68±0.03(stat)±0.04(syst)MeV/c2
are measured using the D 0 → K + K − π + π − and D+(s)→K+K−π+ mode

Study of DsJ decays to D+KS0 and D0K+ final states in pp collisions
No full textA study of D+K0S and D0K+ final states is performed in a sample of 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of s√=7 TeV with the LHCb detector. We confirm the existence of the D∗s1(2700)+ and D∗sJ(2860)+ excited states and measure their masses and widths to be
m(D∗s1(2700)+) = 2709.2±1.9(stat)±4.5(syst) MeV/c2, Γ(D∗s1(2700)+) = 115.8±7.3(stat)±12.1(syst) MeV/c2, m(D∗sJ(2860)+) = 2866.1±1.0(stat)±6.3(syst) MeV/c2, Γ(D∗sJ(2860)+) = 69.9±3.2(stat)±6.6(syst) MeV/c2
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
