The hypertriton in effective field theory [PDF]
Nuclear Physics A, 2002 Doublet Lambda d scattering and the hypertriton are studied in the framework of an effective field theory for large scattering lengths. As in the triton case, consistent renormalization requires a one-parameter three-body force at leading order whose renormalization group evolution is governed by a limit cycle.

Interplay of nuclear physics, effective field theories, phenomenology, and lattice QCD in neutrino physics [PDF]
, 2022 Experiments in neutrino physics cover a wide range—from deep inelastic scattering, over long base-line oscillation experiments and low-energy coherent neutrino–nucleus scattering (CEνNS), to searches for neutrinoless double β decay (0νββ)—yet in all ...

The Lamb shift in muonic hydrogen and the proton radius from effective field theories
, 2015 We comprehensively analyse the theoretical prediction for the Lamb shift in muonic hydrogen, and the associated determination of the proton radius. We use effective field theories.

Soft bootstrap and effective field theories
Journal of High Energy Physics, 2019 The soft bootstrap program aims to construct consistent effective field theories (EFT’s) by recursively imposing the desired soft limit on tree-level scattering amplitudes through on-shell recursion relations.

Loops in AdS: from the spectral representation to position space. Part II
Journal of High Energy Physics, 2021 We continue the study of AdS loop amplitudes in the spectral representation and in position space. We compute the finite coupling 4-point function in position space for the large-N conformal Gross Neveu model on AdS 3.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.

Positivity in massive spin-3/2 EFTs and the Planck-suppressed neighbourhood of supergravity
Journal of High Energy PhysicsIt is well known that a strictly massless spin-3/2 particle can interact consistently only within supergravity. Recently, positivity arguments have shown that an effective field theory of a massive Majorana spin-3/2 particle admits an arbitrarily small ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Ghostbusters: unitarity and causality of non-equilibrium effective field theories
Journal of High Energy Physics, 2020 : For a non-equilibrium physical system defined along a closed time path (CTP), a key constraint is the so-called largest time equation, which is a consequence of unitarity and implies causality.

Amplitude/operator basis in chiral perturbation theory
Journal of High Energy Physics, 2023 We establish a systematic construction of the on-shell amplitude/operator basis for Chiral Perturbation Theory (ChPT) in D = 4 spacetime dimensions and with an arbitrary number of flavors N f .
