Improved exclusion limit for light dark matter from annihilation in NA64
Yu. Andreev, D. Banerjee, J. Bernhard +55
The current most stringent constraints for the existence of sub-GeV dark matter coupling to Standard Model via a massive vector boson were set by the NA64 experiment for…
Hunting down the X17 boson at the CERN SPS
E. Depero, Yu. M. Andreev, D. Banerjee +53
Recently, the ATOMKI experiment has reported new evidence for the excess of events with a mass 17 MeV in the nuclear transitions of He, that they previously obs…
A facility to Search for Hidden Particles (SHiP) at the CERN SPS
SHiP Collaboration, M. Anelli, S. Aoki +233
A new general purpose fixed target facility is proposed at the CERN SPS accelerator which is aimed at exploring the domain of hidden particles and make measurements with tau neutri…
Study of the K- -> mu- nu pi0 decay
I. Ajinenko, S. Akimenko, G. Britvich +27
The decay has been studied using in-flight decays detected with ``ISTRA+'' setup operating in the 25 GeV negative secondary beam of the U-70 PS. Ab…
Observation of the radiative kaon decay K- --> mu-pi0gammanu
O. Tchikilev, S. Akimenko, G. Britvich +18
Using data collected with the ISTRA+ spectrometer during the 2001 run of the U-70 proton synchrotron in Protvino, we report the first observation of the radiative kaon decay K- -->…
The LHCb upgrade I
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1305
The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger th…
Study of the K- -> pi0 e- nu decay
I. Ajinenko, S. Akimenko, G. Akopdzhanov +32
The decay K- -> pi0 e- nu has been studied using in-flight decays detected with "ISTRA+" setup operating at the 25 GeV negative secondary beam of the U-70 PS. About 130K events wer…
Observation of the destructive interference in the radiative kaon decay K- --> mu-nugamma
O. Tchikilev, S. Akimenko, G. Britvich +15
Using data collected with the ISTRA+ spectrometer at U70 proton synchrotron of IHEP, we report the first measurement of the destructive interference in the radiative kaon cecay K-…
Search for light pseudoscalar sgoldstino in K- decays
O. Tchikilev, I. Ajinenko, S. Akimenko +22
A search for the light pseudoscalar sgoldstino production in the three body K- decay K-->pipi0P has been performed with the ISTRA+ detector exposed to the 25 GeV negative secondary…
