Planar three-loop master integrals for 2 → 2 processes with one external massive particle

Journal of High Energy Physics, 2022
We present analytic results for the two tennis-court integral families relevant to 2 → 2 scattering processes involving one massive external particle and massless propagators in terms of Goncharov polylogarithms of up to transcendental weight six.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Study of the weak annihilation contributions in charmless $$\varvec{B_s\rightarrow VV}$$ B s → V V decays

European Physical Journal C: Particles and Fields, 2017
In this paper, in order to probe the spectator-scattering and weak annihilation contributions in charmless $$B_s\rightarrow VV$$ B s → V V (where V stands for a light vector meson) decays, we perform the $$\chi ^2$$ χ 2 -analyses for the endpoint ...

Exact solutions of Einstein-æther gravity in Bianchi type V cosmology

European Physical Journal C: Particles and Fields, 2020
We present the solution space of the field equations in the Einstein-æther theory for the case of a vacuum Bianchi Type V space-time. We also find that there are portions of the initial parameters space for which no solution is admitted by the reduced ...

USP7 inhibits FOXO1 activity in chronic lymphocytic leukaemia cells enhancing cell survival

Molecular Oncology, EarlyView.
CLL cells rely on BCR‐mediated signalling for survival and proliferation in part through suppression of FOXO1. FOXO1 activity is regulated by a plethora of post‐translational modifications including phosphorylation and ubiquitination. We demonstrated that dual inhibition of BCR signalling and the deubiquitinase USP7 activates FOXO1, modulating its ...

Synergies between astroparticle, particle and nuclear physics

, 2019
One overarching objective of science is to further our understanding of the universe, from its early stages to its current state and future evolution. This depends on gaining insight on the universe's most macroscopic components, for example galaxies and

Soft factor structure of MHV amplitudes for massless charged particles

Journal of High Energy Physics
We present a simple derivation of MHV amplitudes in massless spinor and scalar electrodynamics. Working with permutationally invariant amplitudes, we show that they are fully determined by their soft photon behavior and admit a simple factorized form in ...

Study of Nonleptonic Bq∗→DqV and PqD∗ Weak Decays

Advances in High Energy Physics, 2015
Motivated by the powerful capability of measurement for the b hadron decays at LHC and SuperKEKB/Belle-II, the nonleptonic B-∗→DD-∗, Dρ-, DK∗-, πD∗, and KD∗ decays are studied.

Simulation of Activation Experiments in an Irradiation Stand in the Context of Nuclear Decommissioning [PDF]

EPJ Web of Conferences
Monte Carlo simulations are a valuable tool to determine activated areas in nuclear power plants. This paper describes the simulation of an neutron irradiation stand containing 8 (α,n) sources and polyethylene shielding. The source spectrum of beryllium (
