Light Higgs bosons in phenomenological NMSSM

F. Mahmoudi, J. Rathsman, O. Stål +1

We consider scenarios in the next-to-minimal supersymmetric model (NMSSM) where the CP-odd and charged Higgs bosons are very light. As we demonstrate, these can be obtained as simp…

Finite-width effects in the near-threshold ZZZ and ZWW production at ILC

Roman Pasechnik, Vladimir Kuksa

We calculate the cross-section of the near-threshold off-shell and production at the International Linear Collider taking into account their instability and the pri…

Central exclusive quark-antiquark dijet and Standard Model Higgs boson production in proton-(anti)proton collisions

Rafal Maciula, Roman Pasechnik, Antoni Szczurek

We consider the central exclusive production of pairs and Higgs boson at proton-proton collisions at LHC. The amplitude for the process is derived within the …

Nucleon spin structure at low momentum transfers

Roman Pasechnik, Jacques Soffer, Oleg Teryaev

The generalized Gerasimov-Drell-Hearn (GDH) sum rule is known to be very sensitive to QCD radiative and power corrections. We improve the previously developed QCD-inspired model fo…

Polarisation effects in the central exclusive production and the angular distributions

Roman Pasechnik, Antoni Szczurek, Oleg Teryaev

We discuss exclusive elastic double diffractive axial-vector and tensor mesons production for different meson polarisations in proton-(anti)proton collisions…

Spin effects in diffractive charmonia production

Roman Pasechnik, Antoni Szczurek, Oleg Teryaev

We consider exclusive double diffractive production of polarised axial-vector and tensor charmonia in proton-(anti)proton collisions at Tevatron energy. The c…

Production of Light Higgs Pairs in 2-Higgs Doublet Models via the Higgs-strahlung Process at the LHC

M. Moretti, S. Moretti, F. Piccinini +2

At the Large Hadron Collider, we prove the feasibility to detect pair production of the lightest CP-even Higgs boson h of a Type II 2-Higgs Doublet Model through the process q \bar…

Exclusive pair production and irreducible background to the exclusive Higgs boson production

Rafal Maciula, Roman Pasechnik, Antoni Szczurek

We calculated the cross section for the exclusive double diffractive production in reaction at LHC. Large cross sections are obtained (3 -- 10 nb). Th…

QCD rescattering mechanism for diffractive deep inelastic scattering

Roman Pasechnik, Rikard Enberg, Gunnar Ingelman

We present a QCD-based model where rescattering between final state partons in deep inelastic scattering leads to events with large rapidity gaps and a leading proton. In the frame…

Diffractive deep inelastic scattering from multiple soft gluon exchange in QCD

Roman Pasechnik, Rikard Enberg, Gunnar Ingelman

Diffractive hard scattering is interpreted as the effect of soft gluon exchanges between the emerging energetic quarks and the nucleon's color field, resulting in an overall color…

Electromagnetic transition form factors of light vector mesons

Carla Terschluesen, Stefan Leupold

The decays of narrow light vector mesons into pseudoscalar mesons and dileptons are calculated to leading order in a recently proposed scheme which treats pseudoscalar and vector m…
