Supergravity with mimetic dark matter
European Physical Journal C: Particles and Fields, 2021 We formulate a supersymmetric version of gravity with mimetic dark matter. The coupling of a constrained chiral multiplet to $$N = 1$$ N = 1 supergravity is made locally supersymmetric using the rules of tensor calculus.

Chiral Lagrangians for spin-$\frac{1}{2}$ and spin-$\frac{3}{2}$ doubly charmed baryons [PDF]
, 2023 The relativistic chiral Lagrangians for both spin-$\frac{1}{2}$ and spin-$\frac{3}{2}$ doubly charmed baryons are constructed up to the order $\mathcal{O}(p^{4})$.

Light- and strange-quark mass dependence of the ρ(770) meson revisited
Journal of High Energy Physics, 2020 Recent lattice data on ππ-scattering phase shifts in the vector-isovector channel, pseudoscalar meson masses and decay constants for strange-quark masses smaller or equal to the physical value allow us to study the strangeness dependence of these ...

Spontaneous symmetry breaking and Nambu–Goldstone bosons in quantum many-body systems [PDF]
, 2010 Spontaneous symmetry breaking is a general principle that constitutes the underlying concept of a vast number of physical phenomena ranging from ferromagnetism and superconductivity in condensed matter physics to the Higgs mechanism in the standard model

Chiral power counting of one- and two-body currents in direct detection of dark matter
Physics Letters B, 2015 We present a common chiral power-counting scheme for vector, axial-vector, scalar, and pseudoscalar WIMP–nucleon interactions, and derive all one- and two-body currents up to third order in the chiral expansion.

Constraints on disconnected contributions in ππ scattering
Journal of High Energy Physics, 2019 The accuracy of the lattice QCD computation of hadron-hadron scattering at low isospin depends critically on the ability to compute correlation functions with fermionic disconnected Wick contractions.

Navigating collinear superspace
Journal of High Energy Physics, 2020 We introduce a new set of effective field theory rules for constructing Lagrangians with N $$ \mathcal{N} $$ = 1 supersymmetry in collinear superspace. In the standard superspace treatment, superfields are functions of the coordinates x μ θ α θ † α ⋅ $$ \
