Lifetime of the eta' meson at low temperature

E. Perotti, C. Niblaeus, S. Leupold

This work constitutes one part of an investigation of the low-temperature changes of the properties of the eta' meson. In turn these properties are strongly tied to the U(1)_A anom…

SO(10) grand unification in light of recent LHC searches and colored scalars at the TeV-scale

Ufuk Aydemir

We analyze the compatibility of the recent LHC signals and the TeV-scale left-right model(s) in the minimal nonsupersymmetric framework. We show that the models in which t…

Dynamic colour screening in diffractive deep inelastic scattering

Gunnar Ingelman, Roman Pasechnik, Dominik Werder

We present a novel Monte-Carlo implementation of dynamic colour screening via multiple exchanges of semi-soft gluons as a basic QCD mechanism to understand diffractive electron-pro…

Evidence of sub-nucleonic degrees of freedom in J/ 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/ vector mesons in ultra-peripheral heavy ion collisions (UPC) in terms of hadronic interactions. This study was c…

Pati-Salam Unification from Non-commutative Geometry and the TeV-scale boson

Ufuk Aydemir, Djordje Minic, Chen Sun +1

We analyze the compatibility of the unified left-right symmetric Pati-Salam models motivated by non-commutative geometry and the TeV scale right-handed W boson suggested by recent…

Two-Hadron Saturation for the Pseudoscalar-Vector-Vector Correlator and Phenomenological Applications

Tomas Husek, Stefan Leupold

The pseudoscalar-vector-vector correlator is constructed using two meson multiplets in the vector and two in the pseudoscalar channel. The parameters are constrained by the operato…

Color-Kinematics Duality for QCD Amplitudes

Henrik Johansson, Alexander Ochirov

We show that color-kinematics duality is present in tree-level amplitudes of quantum chromodynamics with massive flavored quarks. Starting with the color structure of QCD, we work…

Pair Production of Scalar Leptoquarks at the LHC to NLO Parton Shower Accuracy

Tanumoy Mandal, Subhadip Mitra, Satyajit Seth

We present the scalar leptoquark pair production process at the LHC computed at the next-to-leading order in QCD, matched to the PYTHIA parton shower using the MC@NLO formalism. We…

Prospects for higgsino-singlino dark matter detection at IceCube and PINGU

Rikard Enberg, Shoaib Munir, Carlos Pérez de los Heros +1

We study neutralino dark matter (DM) with large singlino fractions in the next-to-minimal supersymmetric Standard Model (NMSSM). We perform a detailed analysis of the parameter spa…

Light-front representation of chiral dynamics in peripheral transverse densities

C. Granados, C. Weiss

The nucleon's electromagnetic form factors are expressed in terms of the transverse densities of charge and magnetization at fixed light-front time. At peripheral transverse distan…

Quantum-mechanical picture of peripheral chiral dynamics

C. Granados, C. Weiss

The nucleon's peripheral transverse charge and magnetization densities are computed in chiral effective field theory. The densities are represented in first-quantized form, as over…

Perturbative charm production and the prompt atmospheric neutrino flux in light of RHIC and LHC

Atri Bhattacharya, Rikard Enberg, Mary Hall Reno +2

We re-evaluate the prompt atmospheric neutrino flux, using the measured charm cross sections at RHIC and the Large Hadron Collider to constrain perturbative QCD parameters such as…
