Lifetime measurements of low-lying levels in47Sc
TLDR
In this article, the mean lives of low-lying levels in47Sc were measured using the Doppler-shift attenuation method with p-γ coincidences in the 44Ca(α, pγ)47Sc reaction.Abstract:
The mean lives of some low-lying levels in47Sc have been measured using the Doppler-shift attenuation method with p-γ coincidences in the44Ca(α, pγ)47Sc reaction. The following values have been obtained: >8 ps, (4.5±1.6) ps, (90±35) fs, >6 ps, (1.4±0.4) ps, (300±80) fs, (440±80) fs, <70 fs, (570±120) fs, (120±60) fs, (450±170) fs for the levels at 808, 1147, 1297, 1391, 1404, 1798, 1857, 1878, 2002, 2207, 2410 keV, respectively. Branchings of levels were also assigned. The present measurement allows us to propose a nearly complete level scheme for low-lying states in47Sc.M1 transitions are rather fast (of order of 0.1 W.u.) and alsoE1 transitions are not very hindered (of order of few 10−4 W.u.).read more

The anatomy of electroweak symmetry breaking: Tome I: The Higgs boson in the Standard Model
TL;DR: In this paper, the authors focused on the mechanism of electroweak symmetry breaking and the fundamental properties of the Higgs particle of the Standard Model and its decay modes and production mechanisms at hadron colliders and at future lepton colliders.

The Higgs Boson Masses and Mixings of the Complex MSSM in the Feynman-Diagrammatic Approach
TL;DR: In this paper, the full dependence on all relevant complex phases is taken into account, and all the imaginary parts appearing in the calculation are treated in a consistent way, and the renormalization is discussed in detail, and a hybrid on-shell/ scheme is adopted.

Lifetime measurements in sd-shell nuclei : (I). Mean lives of 38Ar levels
TL;DR: In this article, the mean lives of the lowest six excited states in 38Ar were measured with the Doppler shift attenuation method, and the relatively fast decay of the second excited state indicates that positive parity states in the 38Ar are only well described if (ds)−4(fp)2 shell-model configurations are taken into account.

Measurement and interpretation of electromagnetic transitions in 51V
TL;DR: In this paper, the same authors used Coulomb excitation measurements with 32S ions, using a thick 51V target and a Ge(Li) detector, to deduce the B(M1) and B(E2) reduced transition probabilities for the decays of the 0.32, 0.93, 1.61 and 1.81 MeV states.
