Plate tectonics in the microscopy realm: Molecular insights into morphological variability of Peridinium willei (Peridiniales, Dinophyceae)

TAXON, Volume 75, Issue 2, April 2026.
Abstract Freshwater Peridinium willei (Peridiniaceae) is globally distributed, but reports linking its morphologies with DNA sequence data remain scarce. The taxonomy of the species, and its infraspecific taxa, remain ambiguous due to the lack of DNA sequence data for the original and type material.

The simplest B decay, precisely

Journal of High Energy Physics
We derive the QCD×QED factorization theorem governing the leptonic decay B − → μ − ν ¯ μ γ $$ {B}^{-}\to {\mu}^{-}{\overline{\nu}}_{\mu}\left(\gamma \right) $$ at all orders in α s and α.

Revisiting semileptonic B meson decays at next-to-next-to-leading order

Journal of High Energy Physics, 2023
We compute next-to-next-to-leading order corrections to the semileptonic decay rate of B mesons for arbitrary values of the final-state quark mass. For the contribution with one massive quark in the final state, we extend the literature result and obtain

Large methane oxidation across an oxygen gradient in Baltic Sea deep waters

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Robust estimations of methane (CH4) oxidation in marginal seas remain elusive, making CH4 budgets particularly uncertain. Here, we investigate the CH4 benthic source and bottom layer oxidation across the entire Baltic Sea using concentration and stable isotope (δ13C‐CH4) profiles along oxygen and salinity gradients.

Nonleptonic B-meson decays to next-to-next-to-leading order

Journal of High Energy Physics
We compute next-to-next-to-leading order QCD corrections to the partonic processes b → c u ¯ d $$ c\overline{u}d $$ and b → c c ¯ s $$ c\overline{c}s $$ , which constitute the dominant decay channels in standard model predictions for B-meson lifetimes ...

Higgs boson decay into four bottom quarks in the SM and beyond

Journal of High Energy Physics, 2019
We present predictions for the Higgs boson decay into four bottom quarks in the standard model and via light exotic scalars retaining full bottom-quark mass dependence.

Extraction of Effective Parameters From Transverse Momentum Spectra of Heavy Quarkonia in Proton–Proton Collisions at the LHC

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The effective string tension (κ) in the Schwinger mechanism and the effective temperature (T) in Bose–Einstein statistics are extracted from the transverse momentum (pT) spectra of heavy quarkonia produced in proton‐proton (p + p) collisions at the Large Hadron Collider (LHC).

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

Annalen der Physik, Volume 537, Issue 12, December 2025.
 A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

Probing quantum decoherence at Belle II and LHCb

Journal of High Energy Physics
With the advent of Belle II and the LHCb upgrade, the precision measurements of various B-Physics observables are on cards. This holds significant potential for delving into physics beyond the standard model of electroweak interactions.

Complementary constraints on Zb b ¯ $$ Zb\overline{b} $$ couplings at the LHC

Journal of High Energy Physics, 2023
We propose a new strategy to probe the Z boson couplings to bottom and charm quarks at the LHC. In this work we mainly focus on the case of bottom quarks. Here, the Z boson is produced in association with two b-jets and decays to electrons or muons.
