Slovenia has been involved with various big particle physics projects almost as long as it has been a country. Indeed, the first collaboration agreement between CERN and Slovenia dates back to the same year (1991). However, Slovenian physicists were already involved with various particle physics experiments before that time. Nowadays, Slovenian scientific institutions collaborate with the ATLAS experiment at CERN, experiments Belle and Belle II at KEK, and observatory Pierre Auger. Slovenian physicists also organise various Masterclasses, science shows, talks and open days for high-school students, as well as co-coordinate Slovenian Teacher Programmes in connection with CERN.
Slovenija se v svet fizike delcev vključuje skoraj od prvega dne samostojnosti. Prvi sporazum med Slovenijo in CERNom je bil tako sklenjen že leta 1991. Slovenski fiziki pa so bili v razne eksperimente fizike delcev po svetu vključeni že pred tem. Danes razne slovenske raziskovalne institucije v fiziki delcev sodelujejo z eksperimentom ATLAS v CERNu, eksperimentoma Belle in Belle II v KEKu in observatorijem Pierre Auger. Poleg tega slovenski fiziki in fizičarke organizirajo različne Masterclass-e, znanstvene predstave, predavanja in dneve odprtih vrat za dijake in dijakinje. V sodelovanjem s CERNom pa organizirajo tudi programe za slovenske učitelje in učiteljice.
