Higher-order QCD effects for associated WH production and decay at the LHC

Giancarlo Ferrera, Massimiliano Grazzini, Francesco Tramontano

We consider Standard Model Higgs boson production in association with a W boson in hadron collisions. We supplement the fully exclusive perturbative computation of QCD radiative ef…

Neutrino coupling to cosmological background: A review on gravitational Baryo/Leptogenesis

G. Lambiase, S. Mohanty, A. R. Prasanna

In this work we review the theories of origin of matter-antimatter asymmetry in the Universe. The general conditions for achieving baryogenesis and leptogenesis in a CPT conserving…

Nonstandard Higgs Couplings from Angular Distributions in $h \to Z ℓ^{+} ℓ^{-}$

Gerhard Buchalla, Oscar Cata, Giancarlo D'Ambrosio

We compute the fully differential rate for the Higgs-boson decay $h \to Z ℓ^{+} ℓ^{-}$ , with $Z \to ℓ^{^{'} +} ℓ^{^{'} -}$ . For these processes we assume the most general matrix elements…

Polarized Parton Distributions at an Electron-Ion Collider

The NNPDF Collaboration, Richard D. Ball, Stefano Forte +4

We study the potential impact of inclusive deep-inelastic scattering data from a future electron-ion collider (EIC) on longitudinally polarized parton distribution (PDFs). We perfo…

GoSam applications for automated NLO calculations

G. Cullen, H. van Deurzen, N. Greiner +10

We present applications of the program GoSam for the automated calculation of one-loop amplitudes. Results for NLO QCD corrections to beyond the Standard Model processes as well as…

Polarization effects in the cascade decay Lambda_b -> Lambda(-> p pi-) + J/psi(-> l+ l-) in the covariant confined quark model

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

We calculate the invariant and helicity amplitudes for the nonleptonic decay Lambda_b -> Lambda + J/psi, psi(2S) in the covariant confined quark model. We discuss joint angular dec…

Standard Model and New Physics contributions to $K_{L}$ and $K_{S}$ into four leptons

Giancarlo D'Ambrosio, David Greynat, Grégory Vulvert

We study the $K_{L}$ and $K_{S}$ decays into four leptons ( $e e ˉ e e ˉ, μ μ ˉ μ μ ˉ, e e ˉ μ μ ˉ$ ) where we use a form factor motivated by vector meson dominance, and sh…

$W^{\pm}$ bosons production in the quantum statistical parton distributions approach

Claude Bourrely, Franco Buccella, Jacques Soffer

We consider $W^{\pm}$ gauge bosons production in connection with recent results from BNL-RHIC and FNAL-Tevatron and interesting predictions from the statistical parton distribution…

Update of the Binoth Les Houches Accord for a standard interface between Monte Carlo tools and one-loop programs

S. Alioli, S. Badger, J. Bellm +44

We present an update of the Binoth Les Houches Accord (BLHA) to standardise the interface between Monte Carlo programs and codes providing one-loop matrix elements.

NLO QCD corrections to Higgs boson production plus three jets in gluon fusion

G. Cullen, H. van Deurzen, N. Greiner +6

We report on the calculation of the cross section for Higgs boson production in association with three jets via gluon fusion, at next-to-leading-order (NLO) accuracy in QCD, in the…

HW/HZ + 0 and 1 jet at NLO with the POWHEG BOX interfaced to GoSam and their merging within MiNLO

Gionata Luisoni, Paolo Nason, Carlo Oleari +1

We present a generator for the production of a Higgs boson H in association with a vector boson V=W or Z (including subsequent V decay) plus zero and one jet, that can be used in c…

CP violation in D meson decays: would it be a sign of new physics ?

Franco Buccella, Maurizio Lusignoli, Alessandra Pugliese +1

Ascribing the large SU(3) violations in the Cabibbo forbidden decays of neutral D mesons to the final state interactions, one gets large strong phase differences, necessary for sub…

Electroweak Sudakov Corrections to New Physics Searches at the CERN LHC

Mauro Chiesa, Guido Montagna, Luca Barze` +4

We compute the one-loop electroweak Sudakov corrections to the production process Z (nu bar{nu}) + n jets, with n = 1,2,3, in p p collisions at the LHC. It represents the main irre…

Spin-rotation coupling in compound spin objects

G. Lambiase, G. Papini

We generalize spin-rotation coupling to compound spin systems. In the case of muons bound to nuclei in a storage ring the decay process acquires a modulation. Typical frequencies f…
