Strong decays of strange charmed P-wave mesons.
Goldstone boson decays of P-wave D s mesons are studied within the framework of Heavy Hadron Chiral Perturbation Theory. We first analyze the simplest single kaon decays of these strange charmed mesons. We derive a model independent prediction for the width of Ds2 and use experimental information on Ds1 to constrain the S-wave contribution to D 1 decay. Single and double pion decay modes are th...
متن کاملRadiative decays of the (0, 1) strange-bottom mesons
In this article, we assume that the (0, 1) strange-bottom mesons are the conventional bs̄ mesons, and calculate the electromagnetic coupling constants d, g1, g2 and g3 using the light-cone QCD sum rules. Then we study the radiative decays Bs0 → B sγ, Bs1 → Bsγ, Bs1 → B sγ and Bs1 → Bs0γ, and observe that the widths are rather narrow. We can search for the (0, 1) strange-bottom mesons in the inva...
متن کاملMeasurements of direct CP violating asymmetries in charmless decays of strange bottom mesons and bottom baryons.
We report measurements of direct CP-violating asymmetries in charmless decays of neutral bottom hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding to 1 fb(-1) of integrated luminosity, we obtain the first measurements of direct CP violation in bottom strange mesons, A(CP)(B(s)(0)→K(-)π(+))=+0.39±0.15(stat)±0.08(sys...
متن کاملProperties of the Charmed P-wave Mesons
Two broad charmed mesons, the D∗ 0 and D ′ 1, have recently been observed. We examine the quark model predictions for the D∗ 0 and D ′ 1 properties and discuss experimental measurements that can shed light on them. We find that these states are well described as the broad, j = 1/2 non-strange charmed P -wave mesons. Understanding the D∗ 0 and D ′ 1 states can provide important insights into the...
متن کاملCharmed-strange Mesons Experimental Results
Two new states in the charm strange sector, D∗sJ(2317) + and DsJ(2460), have recently been discovered at e+e− collider experiments. The new states are first observed in the dominant Ds π0 and D∗+ s π0 modes respectively and are very narrow. They are consistent with 0+ and 1+ P-wave cs mesons. The DsJ(2460) meson is also observed in Ds γ and Ds π+π− modes. A review of the discoveries and possibl...
