/
Giudice, Gian F.
(CERN) ;
McCullough, Matthew
;
Teresi, Daniele
At colliders massive long-lived charged particles could be revealed through their anomalously large ionisation energy loss $dE/dx$. [...]

On the NLO QCD Corrections to Gluon-Initiated ZH Production
/
Degrassi, Giuseppe
(INFN, Rome3 ; Rome III U.) ;
Gröber, Ramona
;
Vitti, Marco
;
Zhao, Xiaoran
We compute the QCD corrections at next-to-leading order for the process $gg \rightarrow ZH$, including both the virtual two-loop terms and real-emission contributions. [...]

PBH assisted search for QCD axion dark matter
/
Choi, Gongjun
(CERN) ;
Schiappacasse, Enrico D.
(Jyvaskyla U. ; Helsinki Inst. of Phys. ; Rice U.)
The entropy production prior to BBN era is one of ways to prevent QCD axion with the decay constant $F_{a}\in[10^{12}{\rm GeV},10^{16}{\rm GeV}]$ from overclosing the universe when the misalignment angle is $\theta_{\rm i}=\mathcal{O}(1)$. [...]

(Minnesota U., Theor. Phys. Inst.) ;
Mambrini, Yann
;
Olive, Keith A.
We consider the generation of the baryon asymmetry in models with right-handed neutrinos produced through gravitational scattering of the inflaton during reheating. [...]

Domcke, Valerie
(CERN ; EPFL, Lausanne, LPPC) ;
Harigaya, Keisuke
(CERN ; Tokyo U., IPMU) ;
Mukaida, Kyohei
(KEK, Tsukuba ; Sokendai, Tsukuba)
We consider the transfer of a U(1) charge density between Bose-Einstein condensates of complex scalar fields coupled to a thermal bath, focusing on the case of a homogeneous Affleck-Dine field transmitting the charge stored in its angular motion to an axion field. [...]

;
McLeod, Andrew J.
;
Wilhelm, Matthias
We bootstrap the three-point form factor of the chiral stress-tensor multiplet in planar $\mathcal{N}=4$ supersymmetric Yang-Mills theory at six, seven, and eight loops, using boundary data from the form factor operator product expansion. [...]
