Extraction of the Muon Signals Recorded with the Surface Detector of the Pierre Auger Observatory Using Recurrent Neural Networks

The Pierre Auger Collaboration, A. Aab, P. Abreu +370

The Pierre Auger Observatory, at present the largest cosmic-ray observatory ever built, is instrumented with a ground array of 1600 water-Cherenkov detectors, known as the Surface…

Measurement of the fluctuations in the number of muons in extensive air showers with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +365

We present the first measurement of the fluctuations in the number of muons in extensive air showers produced by ultrahigh energy cosmic rays. We find that the measured fluctuation…

b-tagging in DELPHI at LEP

The DELPHI Collaboration, J. Abdallah

The standard method used for tagging b-hadrons in the DELPHI experiment at the CERN LEP Collider is discussed in detail. The main ingredient of b-tagging is the impact parameters o…

Determination of |Vub|/|Vcb| with DELPHI at LEP

The DELPHI Collaboration, P. Abreu

The ratio of the CKM quark-mixing matrix elements |Vub|/|Vcb| has been measured using B hadron semileptonic decays. The analysis uses the reconstructed mass M_X of the secondary ha…

Rapidity-Rank Structure of p pbar Pairs in Hadronic Z0 Decays

The DELPHI Collaboration, P. Abreu

The rapidity-rank structure of p pbar pairs is used to analyze the mechanism of baryon production in hadronic Z0 decay. The relative occurrence of the rapidity-ordered configuratio…

Measurement of V_{cb} from the decay process \bar{B^0} -> D^{*+} \ell^- \barν

The DELPHI Collaboration, P. Abreu

A new precise measurement of |V_{cb}| and of the branching ratio BR(\bar{B^0} -> D^{*+} \ell^- \bar{ν_\ell}) has been performed using a sample of about 5000 semileptonic decays \ba…
