SciPost Physics Proceedings, 2022 We discuss the analytic structure of the master integrals relevant for computing the com- plete set of leading-colour analytic helicity amplitudes for top-quark pair production via gluon fusion at two loops in QCD.

Finite density QCD via imaginary chemical potential
, 2002 We study QCD at nonzero temperature and baryon density in the framework of the analytic continuation from imaginary chemical potential. We carry out simulations of QCD with four flavor of staggered fermions, and reconstruct the phase diagram in the ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric Blood &Cancer, EarlyView.ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

New series representations for the two-loop massive sunset diagram
European Physical Journal C: Particles and Fields, 2020 We derive new convergent series representations for the two-loop sunset diagram with three different propagator masses $$m_1,\, m_2$$ m1,m2 and $$m_3$$ m3 and external momentum p by techniques of analytic continuation on a well-known triple series that ...

Holomorphic Continuation of Functions Along a Fixed Direction (Survey)
Современная математика: Фундаментальные направления, 2022 In this article, we give an overview of the most significant and important results on holomorphic extensions of functions along a fixed direction. We discuss the following geometric questions of multidimensional complex analysis: • holomorphic extension ...

Rigorous Analysis of Singularities and Absence of Analytic Continuation at First Order Phase Transition Points in Lattice Spin Models [PDF]
, 2003 We report about two new rigorous results on the non-analytic properties of thermodynamic potentials at first order phase transition. The first one is valid for lattice models ($d\geq 2$) with arbitrary finite state space, and finite-range interactions ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

International Journal of Mathematics and Mathematical Sciences, 1992 Let f(z)=∑k=0∞akzk, a0≠0 be analytic in the unit disc. Any infinite complex vector θ=(θ0,θ1,θ2,…) such that |θk|=1, k=0,1,2,…, induces a function fθ(z)=∑k=0∞akθkzk which is still analytic in the unit disc.
