Enhancement of associated H^\pm W^\mp production in the NMSSM

R. Enberg, R. Pasechnik, O. Stål

We study the associated production of a charged Higgs and a W boson in high-energy pp collisions at the Large Hadron Collider. This is an interesting process for charged Higgs disc…

Electromagnetic Transition Form Factors of Mesons

Carla Terschlüsen, Stefan Leupold

Using a counting scheme which treats pseudoscalar and vector mesons on equal footing, the decays of the narrow light vector mesons omega and phi into a dilepton and a pseudoscalar…

Large Mixing Angles From Many Right-Handed Neutrinos

Brian Feldstein, William Klemm

A beautiful understanding of the smallness of the neutrino masses may be obtained via the seesaw mechanism, whereby one takes advantage of the key qualitative distinction between t…

Description of fully differential Drell-Yan pair production

Fabian Eichstaedt, Stefan Leupold, Kai Gallmeister +2

We investigate Drell-Yan pair production in a QCD inspired model, which takes into account all relevant hard processes up to . To address the known shortfalls of such a fix…

Exclusive production of χ_{c}(0^{+}) meson and its measurement in the π^{+}π^{-} channel

Piotr Lebiedowicz, Roman Pasechnik, Antoni Szczurek

We report on the results of a theoretical study of the central exclusive production of scalar meson via decay in high-energy hadron collision…

Constraints on Enhanced Dark Matter Annihilation from IceCube Results

Ivone F. M. Albuquerque, Leandro J. Beraldo e Silva, Carlos Pérez de los Heros

Excesses on positron and electron fluxes measured by ATIC, and the PAMELA and Fermi--LAT telescopes can be explained by dark matter annihilation in our Galaxy. However, this requir…

Four-loop QCD analysis of the Bjorken sum rule vs data

V. L. Khandramai, R. S. Pasechnik, D. V. Shirkov +2

We study the polarized Bjorken sum rule at low momentum transfers in the range with the four-loop NLO expression for the coefficient function $C_{\rm Bj…

Associated central exclusive production of charged Higgs bosons

Rikard Enberg, Roman Pasechnik

We propose central exclusive production of a charged Higgs boson in association with a W boson as a possible signature of certain types of extended Higgs sectors. We calculate the…

Tests of the fundamental symmetries in eta meson decays

Andrzej Kupsc, Andreas Wirzba

Patterns of chiral symmetry violation and tests of the conservation of the fundamental C, P and CP symmetries are key physics issues in studies of the pi0, eta and eta' meson decay…

Measurement of exclusive production of scalar meson in proton-(anti)proton collisions via decay

Piotr Lebiedowicz, Roman Pasechnik, Antoni Szczurek

We consider a measurement of exclusive production of scalar meson in the proton-proton collisions at LHC and RHIC and in the proton-antiproton collisions at the Tev…

Phase diagram of chirally imbalanced QCD matter

M. N. Chernodub, A. S. Nedelin

We compute the QCD phase diagram in the plane of the chiral chemical potential and temperature using the linear sigma model coupled to quarks and to the Polyakov loop. The chiral c…
