Multi-field oscillons/I-balls in the Friedberg-Lee-Sirlin model
Kai Murai, Tatsuya Ogawa, Fuminobu Takahashi
We study oscillon/I-ball solutions in a real scalar version of the Friedberg-Lee-Sirlin (FLS) model. Using the multiple-scale analysis, we derive the conditions for oscillon soluti…

We revisit the upper bound on the annihilation cross-section, of a stable dark matter (DM) of mass GeV by considering five different channels: $W^+…
Higher-order QCD and electroweak corrections for production
Nikolaos Kidonakis, Nodoka Yamanaka
We calculate higher-order soft-gluon corrections for the associated production of a top-antitop quark pair and a Higgs boson ( production) using resummation in one-part…
The quantum criticality of the Standard Model and the hierarchy problem
Juan P. Garcés, Florian Goertz, Manfred Lindner +1
The naturalness principle has long guided efforts to understand physics beyond the Standard Model, with the hierarchy problem as the central issue. We revisit the role of quantum c…

At nonzero temperatures, the deconfining phase transition can be analyzed using an effective matrix model to characterize the change in holonomy. The model includes gluons and two-…
Tripling Fluctuations and Peaked Sound Speed in Fermionic Matter
Hiroyuki Tajima, Kei Iida, Toru Kojo +1
A crossover involving three-fermion clusters is relevant to the hadron-quark crossover, which, if occurring in a neutron star, could naturally reproduce the dense-matter equation o…
In-medium electromagnetic form factors of pseudoscalar mesons from the quark model
