Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Complementary Probes of the Dimension‐6 Operator via Gravitational Waves and Multi‐Higgs Production

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
We investigate the phenomenological consequences of a dimension‐6 operator H†H3/Λ2, Λ is the effective scale at which new physics takes over, which modifies the scalar potential of the standard model and can induce a strong first‐order electroweak phase transition (SFOEWPT). We estimate the lower limit on the effective scale Λ to be 515 GeV from the di‐

Quark number scaling of hadronic pT spectra and constituent quark degree of freedom in p–Pb collisions at sNN=5.02 TeV

Physics Letters B, 2017
We show that the experimental data of transverse momentum (pT) spectra of identified hadrons released recently by ALICE collaboration for p–Pb collisions at sNN=5.02 TeV exhibit a distinct universal behavior — the quark number scaling.

Viscous QCD medium effects on the bottom quark transport coefficients

European Physical Journal C: Particles and Fields, 2023
The bottom quark transport coefficients, i.e., drag and diffusion coefficients, have been studied for the collisional and soft gluon radiative processes within the viscous QCD medium.

Extraction of Effective Parameters From Transverse Momentum Spectra of Heavy Quarkonia in Proton–Proton Collisions at the LHC

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The effective string tension (κ) in the Schwinger mechanism and the effective temperature (T) in Bose–Einstein statistics are extracted from the transverse momentum (pT) spectra of heavy quarkonia produced in proton‐proton (p + p) collisions at the Large Hadron Collider (LHC).

Heavy-ion physics and quark-gluon plasma [PDF]

, 2006
This is the report of Heavy Ion Physics and Quark-Gluon Plasma at WHEPP-09 which was part of Working Group-4. Discussion and work on some aspects of quark-gluon plasma believed to have created in heavy-ion collisions and in early Universe are ...

“QGP Signatures” revisited

European Physical Journal C: Particles and Fields
We revisit the graphic table of QCD signatures in our 1996 Annual Reviews article “The Search for the Quark–Gluon Plasma” and assess the progress that has been made since its publication towards providing quantitative evidence for the formation of a ...

Adiabatic hydrodynamization in rapidly-expanding quark–gluon plasma

Physics Letters B, 2021
We propose a new scenario characterizing the transition of the quark–gluon plasma (QGP) produced in heavy-ion collisions from a highly non-equilibrium state at early times toward a fluid described by hydrodynamics at late times.
