Semileptonic decays $Λ_{c}^{+} \to Λ ℓ^{+} ν_{ℓ} (ℓ = e, μ)$ in the covariant quark model and comparison with the new absolute branching fraction measurements of Belle and BESIII

Thomas Gutsche, Mikhail A. Ivanov, Jurgen G. Korner +2

We present precise theoretical predictions for the absolute branching fractions of $Λ_{c}^{+} \to Λ ℓ^{+} ν_{ℓ} (ℓ = e, μ)$ decays in the covariant confined quark model. This study i…

Towards an assessment of the ATLAS data on the branching ratio Gamma(Lambda_b(0) -> psi(2S) Lambda(0))/Gamma(Lambda_b(0) -> J/psi Lambda(0))

Thomas Gutsche, Mikhail A. Ivanov, Jurgen G. Korner +2

Recently the ATLAS Collaboration at CERN reported on the measurement of the branching ratio R(Lambda_b) = Gamma(Lambda_b(0) -> psi(2S) Lambda(0))/Gamma(Lambda_b(0) -> J/psi Lambda(…

Evidence of sub-nucleonic degrees of freedom in J/ $ψ$ photoproduction in ultraperipheral collisions at the CERN Large Hadron Collider

E. Andrade-II, I. González, A. Deppman +1

We present calculations for the incoherent photoproduction of J/ $ψ$ vector mesons in ultra-peripheral heavy ion collisions (UPC) in terms of hadronic interactions. This study was c…

Exotic see-saw mechanism for neutrinos and leptogenesis in a Pati-Salam model

Andrea Addazi, Massimo Bianchi, Giulia Ricciardi

We discuss non-perturbative corrections to the neutrino sector, in the context of a D-brane Pati-Salam-like model, that can be obtained as a simple alternative to $S O (10)$ GUT's in…

Physical observables in the decay $Λ_{b} \to Λ_{c} (\to Λ + π) + τ^{-} + ν ˉ_{τ}$

Nurgul Habyl, Thomas Gutsche, Mikhail A. Ivanov +3

We analyze the tauonic semileptonic baryon decays $Λ_{b}^{0} \to Λ_{c}^{+} + τ^{-} + ν ˉ_{τ}$ with particular emphasis on the lepton helicity flip contributions which vanish for zero lepto…

Decaying Leptophilic Dark Matter at IceCube

Sofiane M. Boucenna, Marco Chianese, Gianpiero Mangano +4

We present a novel interpretation of IceCube high energy neutrino events (with energy larger than 60 TeV) in terms of an extraterrestrial flux due to two different contributions: a…

Chances for SUSY-GUT in the LHC Epoch

Zurab Berezhiani, Marco Chianese, Gennaro Miele +1

The magic couple of SUSY and GUT still appears the most elegant and predictive physics concept beyond the Standard Model. Since up to now LHC found no evidence for supersymmetric p…

Assuming Regge trajectories in holographic QCD: from OPE to Chiral Perturbation Theory

Luigi Cappiello, Giancarlo D'Ambrosio, David Greynat

The soft wall model in holographic QCD has Regge trajectories but wrong operator product expansion (OPE) for the two-point vectorial QCD Green function. We modify the dilaton poten…

A facility to Search for Hidden Particles at the CERN SPS: the SHiP physics case

Sergey Alekhin, Wolfgang Altmannshofer, Takehiko Asaka +82

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (Search for Hidden Particles) experiment is intended to hunt for new physics in the larg…

Addressing the LHC flavour anomalies with horizontal gauge symmetries

Andreas Crivellin, Giancarlo D'Ambrosio, Julian Heeck

We study the impact of an additional $U (1)^{'}$ gauge symmetry with flavour-dependent charges for quarks and leptons on the LHC flavour anomalies observed in $B \to K^{*} μ^{+} μ^{-}$ , $R(K)…

Self-induced flavor instabilities of a dense neutrino stream in a two-dimensional model

Alessandro Mirizzi, Gianpiero Mangano, Ninetta Saviano

We consider a simplifed model for self-induced flavor conversions of a dense neutrino gas in two dimensions, showing new solutions that spontaneously break the spatial symmetries o…

Some conclusive considerations on the comparison of the ICARUS nu_mu to nu_e oscillation search with the MiniBooNE low-energy event excess

M. Antonello, B. Baibussinov, P. Benetti +51

A sensitive search for anomalous LSND-like nu_mu to nu_e oscillations has been performed by the ICARUS Collaboration exposing the T600 LAr-TPC to the CERN to Gran Sasso (CNGS) neut…

Higgs boson decay into b-quarks at NNLO accuracy

Vittorio Del Duca, Claude Duhr, Gabor Somogyi +2

We compute the fully differential decay rate of the Standard Model Higgs boson into b-quarks at next-to-next-to-leading order (NNLO) accuracy in alpha_S. We employ a general subtra…

The semileptonic decay Lambda_b -> Lambda_c + tau(-) + antinu_tau in the covariant confined quark model

Thomas Gutsche, Mikhail A. Ivanov, Jurgen G. Korner +3

Recently there has been much interest in the tauonic semileptonic meson decays B -> D + tau + nu_tau and B -> D* + tau + nu_tau where one has found larger rates than what is predic…
