Precision measurements with cold neutrons

Free Evolution While the biggest part of the phase shift accumulated in the interferometer sequence is due to light interaction, understanding the effect of external fields acting

The top quark pair production cross section measurement using kinematic information only in the lepton + jets channel analyses 0.7 fb −1 of 2011 collision data.. This analysis is

For the backgrounds normalised using CRs (WW for the N jet = 0 and N jet = 1 analyses and top in the N jet = 1 and ≥ 2 analyses), the sources of uncertainty can be grouped into

This analysis also probes the spin and parity (J P ) using the H → ZZ (∗) → 4` decay, through the observed distributions of the two Z (∗) boson masses, one production angle and

One of the largest theoretical uncertainties assigned to the strong coupling constant α s as determined from hadronic tau decays [2,3,4,5] (for recent reviews see [6,7,8,9,10,11])

− The per event mass uncertainty for the events in the signal region is estimated in two ways: firstly by using the high statistics data samples mentioned above, and secondly by

During the course of this thesis, measurements were carried out on the prototype to check the precision of various me- chanical elements such a reference inserts or the module
