We study the decays B → K(∗)l+l− and Bs → l+l− (l = e, μ) in the minimal supersymmetric standard model with R-parity violation (RPV). From the recent measurements of their branching ratios, we have derived new upper bounds on the relevant RPV coupling products, which are stronger than the existing ones. Using the constrained parameter space, we predict the RPV effects on the forward-backward as...

We review a recent global analysis of inclusive single-charged-hadron production in high-energy colliding-beam experiments, which is performed at nextto-leading order (NLO) in the parton model of quantum chromodynamics endowed with nonperturbative fragmentation functions (FFs). Comparisons of pp data from CERN SppS and the Fermilab Tevatron and γp data from DESY HERA with the corresponding NLO ...

Using the example of selected decays driven by R-parity-violating supersymmetric operators, we demonstrate how strong final-state interactions can be controlled quantitatively with high precision, thus allowing for a more accurate extraction of effective parameters from data. In our examples we focus on the lepton-flavor-violating decays τ → μπ+π−. In R-parity violation these can arise due to t...

This talk summarizes recent QCD results from HERA, the Tevatron Collider and Tevatron xed target experiments.

In the framework of the littlest Higgs model with T-parity (LHT), we study the production processes of T-even (T+) and T-odd (T−) partners of the top quark at the Large Hadron Collider (LHC). We show that the signal events can be distinguished from the standard-model backgrounds, and that information about mass and mixing parameters of the top partners can be measured with relatively good accur...

In supersymmetric extensions of the standard model, particles may be assigned a new quantum number called R-parity (Rp) [1]. The particles of the standard model are Rp even, and their corresponding superpartners are Rp odd. The bounds on possible Rp-violating couplings are relatively restrictive for the first two generations of quarks and leptons, but much less so for states of the third genera...

Deep-inelastic diffractive scaling provides fundamental insight into the QCD pomeron. It is argued that single gluon domination of the structure function, together with the well-known Regge pole property, determines that the pomeron carries color-charge parity Cc = −1 and, at short distances, is in a super-critical phase of Reggeon Field Theory. The main purpose of the talk is to describe the r...

Low energy supersymmetry with bilinear breaking of R-parity leads to a weak-scale seesaw mechanism for the atmospheric neutrino scale and a radiative mechanism for the solar neutrino scale. The model has striking implications for collider searches of supersymmetric particles. Assuming that the lightest SUSY particle is the lightest neutralino we demonstrate that (i) The neutralino decays inside...

Studies of the spin and parity quantum numbers of the Higgs boson in the WW ∗→ eνμν final state are presented, based on proton–proton collision data collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb−1 at a centre-ofmass energy of √ s = 8 TeV. The Standard Model spinparity JCP = 0++ hypothesis is compared with alternative hypothese...
