Gravitational form factors of the -boson
P. Beißner, J. Yu. Panteleeva, B. -D. Sun +2
Matrix elements of the energy-momentum tensor for one-particle states of the -boson are parameterized in terms of gravitational form factors. One-loop order electroweak correcti…
Scrutiny of the new class of three-nucleon forces
E. Epelbaum, A. M. Gasparyan, J. Gegelia +2
In a recent publication, Cirigliano {\it et al.} [Phys. Rev. Lett. 135, 022501 (2025)] argue that three-nucleon forces (3NFs) involving short-range operators that couple two pions…
Implications of spin symmetry for XYZ states
Q. Wang, V. Baru, E. Epelbaum +4
Numerous exotic candidates containing a heavy quark and anti-quark (the so-called states) have been reported since the observation of the in 2003. For these systems…
Spin partners of the and revisited
V. Baru, E. Epelbaum, A. A. Filin +2
We study the implications of the heavy-quark spin symmetry for the possible spin partners of the exotic states and in the spectrum of bottomonium. We form…
New fixed points of the renormalisation group for two-body scattering
M. C. Birse, E. Epelbaum, J. Gegelia
We outline a separable matrix ansatz for the potentials in effective field theories of nonrelativistic two-body systems with short-range interactions. We use this ansatz to constru…
Quark mass dependence of the X(3872) binding energy
V. Baru, E. Epelbaum, A. A. Filin +3
We explore the quark-mass dependence of the pole position of the X(3872) state within the molecular picture. The calculations are performed within the framework of a nonrelativisti…
A new EFT approach to NN scattering problem
E. Epelbaum, J. Gegelia
We present the new, modified Weinberg approach to the NN scattering problem in effective field theory. Issues of renormalization are briefly discussed and the results of LO calcula…
Weinberg's approach to nucleon-nucleon scattering revisited
E. Epelbaum, J. Gegelia
We propose a new, renormalizable approach to nucleon-nucleon scattering in chiral effective field theory based on the manifestly Lorentz invariant form of the effective Lagrangian…
Regularization, renormalization and "peratization" in effective field theory for two nucleons
E. Epelbaum, J. Gegelia
We discuss conceptual aspects of renormalization in the context of effective field theories for the two-nucleon system. It is shown that, contrary to widespread belief, renormaliza…
