, 2014 We review recent results from the LHCb experiment on studies of particle decays that are forbidden or rare in the Standard Model. The studies include searches for lepton flavour violating decays of the $\tau$ lepton and the $B$ and $D$ mesons, and of $B$

Advances in Halide Perovskites for Photon Radiation Detectors
Advanced Materials Technologies, EarlyView.This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Advanced Materials Technologies, EarlyView.ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

A comprehensive study of ALPs from B-decays
Journal of High Energy PhysicsWe present a comprehensive study of axion-like particles (ALPs) through flavor changing neutral current processes, such as B → Ka followed by a → hadronic, γγ, μ + μ − channels. Our generic framework encompasses different ultraviolet scenarios similar to

Advanced Materials Technologies, EarlyView.Here, two types of electronic components are presented: a strain sensor and a stable resistor. Electrofluids properties are tuned to match these behaviors by selecting the type of filler. We show that the morphology of the filler together with its oxygen content are the key parameters to create electrical and mechanical networks with distinct responses.

TeV-scale scalar leptoquarks motivated by B anomalies improve Yukawa unification in SO(10) GUT
Journal of High Energy PhysicsIt is common practice to explain deviations between data and Standard-Model (SM) predictions by postulating new particles at the TeV scale ad-hoc. This approach becomes much more convincing, if one successfully embeds the postulated particles into a UV ...

Non-factorisable contributions of strong-penguin operators in Λ b → Λℓ + ℓ − decays
Journal of High Energy PhysicsWe investigate for the first time a certain class of non-factorisable contributions of the four-quark operators O $$ \mathcal{O} $$ 3−6 in the weak effective Hamiltonian to the Λ b → Λℓ + ℓ − decay amplitude.

Potential of discovering Ξcc+ in Λb decays
Physics Letters BWe propose to search for Ξcc+ in the decay Λb→Ξcc+D−, which serves as a tagged and reconstructible source of Ξcc+. A possible fully charged final state is [(pK−K−π+)Ξc0π+]Ξcc+(K+π−π−)D−, where the subscripts indicate the parent hadron in the decay chain.
