This thesis studies at the ultimate size of the flavor-mixing section in decays of strange-bottom mesons (B_s) into J/psi and phi mesons played in high-energy proton-antiproton collisions recorded via the Collider scan at Fermilab. Interference happens among direct decays and decays following digital particle-antiparticle transitions (B_s-antiB_s). The part distinction among transition amplitudes (“mixing phase”) is observable and intensely delicate to contributions from non-standard-model debris or interactions which may be very challenging to observe another way – a incontrovertible fact that makes the suitable dimension of the B_s blending part some of the most very important ambitions of particle physics. the consequences offered contain an actual decision of the blending section and a set of different vital supplementary effects. All measurements are one of the such a lot certain on hand from a unmarried test and supply considerably more desirable constraints at the phenomenology of latest debris and interactions.

Resuscitate! Second Edition: How Your Community Can Improve Survival from Sudden Cardiac Arrest
Surprising cardiac arrest is the top reason for dying between adults, but it needn't be deadly. although survival in so much groups is especially bad, a couple of groups in attaining charges as excessive as 50%. Why are a few groups such a success in snatching lifestyles from the jaws of demise? Resuscitate! describes the stairs any EMS procedure can take to enhance cardiac arrest survival.

Then the beam transverse-profile was shaped to its optimized configuration by mean of iron plates which acted as collimators and trimmed the transverse beam-halo. The interaction region had a roughly Gaussian distribution in both transverse (ψT ≈ 30 µm) and longitudinal (ψz ≈ 28 cm) planes approximately centered in the nominal interaction point. When the beam profile was narrow enough and the conditions were safely stable, the detectors were powered and data taking started. 2 × 1032 cm−2 s−1 , because of the beam-gas and beam-halo interactions.
