Prompt neutrinos and intrinsic charm at SHiP

Journal of High Energy Physics, 2019
We present a new evaluation of the far-forward neutrino plus antineutrino flux and number of events from charm hadron decays in a 400 GeV proton beam dump experiment like the Search for Hidden Particles (SHiP).

Heavy Quark Symmetry Violation in Semileptonic Decays of D Mesons

, 1992
The decays of $D$ mesons to $K l \nu$ and $K^* l \nu$ final states exhibit significant deviations from the predictions of heavy-quark symmetry, as one might expect since the strange quark's mass is of the same order as the QCD scale.

Heavy Quarkonium States With Baryonic Chemical Potential

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential. The binding energies of the quarkonium states has been obtained by using quasiparticle Debye mass which further depends on temperature and baryonic chemical potential (μb ...

Revisiting $$B\rightarrow K^*\pi $$ B → K ∗ π and $$B\rightarrow K\rho $$ B → K ρ decays using the modified perturbative QCD approach

European Physical Journal C: Particles and Fields
We revisit $$B\rightarrow K^*\pi $$ B → K ∗ π and $$B\rightarrow K\rho $$ B → K ρ decay processes using the modified perturbative QCD approach, which is developed based on the perturbative QCD approach with a few improvements.

Holographic CBK relation

Physics Letters B, 2018
The Crewther–Broadhurst–Kataev (CBK) relation connects the Bjorken function for deep-inelastic sum rules (or the Gross–Llewellyn Smith function) with the Adler function for electron–positron annihilation in QCD; it has been checked to hold up to four ...

Holographic Duals of Symmetry Broken Phases

Fortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract A novel interpretation of Symmetry Topological Field Theories (SymTFTs) as theories of gravity is explored by proposing a holographic duality where the bulk SymTFT (with the gauging of a suitable Lagrangian algebra) is dual to the universal effective field theory (EFT) that describes spontaneous symmetry breaking on the boundary.

A new determination of higher-order QCD corrections to hadronic τ decays

Physics Letters B
We employ Levin-type sequence transformations to accelerate the convergence of the perturbative fixed-order expansion of the QCD correction δ(0) in terms of the strong coupling αs.

Perturbative and non-perturbative QCD

, 2006
In these lectures we give a concise introduction to the ideas of renormalon calculus in QED and QCD. We focus in particular on the example of the Adler D function of vacuum polarization, and on relations between perturbative renormalon ambiguities and corresponding non-perturbative Operator Product Expansion (OPE) ambiguities.

Analysing the impacts of extreme torrential events using multi‐temporal LiDAR datasets—The Schöttlbach catchment, Upper Styria, Austria

Earth Surface Processes and Landforms, Volume 49, Issue 9, Page 2809-2824, July 2024.
The Schöttlbach catchment recorded two major flood events in July 2011 and August 2017. On the basis of reports, geomorphic mapping and the analysis of multi‐temporal LiDAR datasets, we tried to analyse the impacts on the local geomorphic system and constructed an event‐scaled sediment budget for the 2017 event. Abstract Extreme precipitation events in

Perturbative QCD analysis of $B \to \phi K^* $ decays

, 2002
We study the first observed charmless $B\to VV$ modes, the $B\to\phi K^*$ decays, in perturbative QCD formalism. The obtained branching ratios $B(B\to\phi K^*)\sim 15 \times 10^{-6}$ are larger than $\sim 9\times 10^{-6}$ from QCD factorization.
